* 2017 problems

** ssd error on laptop

** paint mode not complete enough

** many mistakes where unset sticky devattrs would just use last-set value and the effect would look different later

** putting in 8 flashes of the same lights and same note tint color takes a huge amount of work. Add-momentary might have helped but it did nothing

** rdfdb file watcher breaks a lot and drops files. emacs focus-autosave may have made this worse. No workaround less than restarting rdfdb then all its dependents

*** the dependents ought to resync without a restart

*** rdfdb should have a UI showing loaded files and any parse errors

** bug in timeline loading note tint colors

** given a multicolor static effect, I'd like a way to quickly animate it by rotating hues, chase, blink, etc

** output fps is not great, many fades are bumpy

** effectsequencer gets behind running graph patches at 100ms each. They should be coalesced by rdfdb so ES never gets behind

** can't edit an existing effect in /live because it's not reading and writing rdf data like KC and /timeline do. /live should edit an unnamed-or-named effect just like other tools. Rename /live to effectedit

** ballyhoo light moves look lumpy- lights seem to speed up and slow down

** chrome stalls on page loads sometimes with 'resolving host', but the host is in /etc/hosts and there's no route to another DNS

** would be nice to be able to preview audio in the booth, maybe on a different asco screen so I don't accidentally play the next stage song in the booth #nomodes

** computer times might be 100ms off, and i don't know how to sync them without internet

** show had 2-3 cases where it would be nice to have a follow spot do a programmed move

** get a keyboard/trackpad combo for the 2ary box- fitting a normal mouse on the table is hard

** asco doesn't autoreconnect (nor does much else), and this means i can't do wall-mounted tablets backstage

** rdfdb shows tons of http11clientfactory stopping, which probably isn't great. move to zmq or grpc or fix the http to keepalive better. maybe i'm sending more concurrent requests than i have connections in my pool? patch coalescing should help that.

** besides being low frame rate, manual fades on KC kind of crash into black. they could probably use a better transfer function somewhere in the pipeline, maybe in the effect

** near the end of 2nd show, enttec dmx seemed to just stop outputting. stats shows no more writes happening. dmesg says nothing. restarted collector and it's counting writes again. no idea how that got jammed.

New timeline layout:

A separate web page per song. 'Follow song' means go to the right page

when song changes (but you could press browser-back to go back).

When starting up, zoom the time to fit the song (current one doesn't do this).

Timeline includes vidref playback. Maybe it slides along with time

cursor so bystanders can obviously tell if we're going forward or

back. Or just put annotations on the video to show how it's moving.

Perhaps use a row of timeline to show thumbs of the dance, for finding

sections even faster.

New elements:

light9-effect-scale (for use in KC and timeline attrs)

  effect name

  big or normal colorvalue slider. Light up on non-zero values. Support KC mouse bindings.

  value number

  optional hue/sat widget

  optional editable effect uri

light9-device-settings (for effectedit)

  device and class

  each attr row has a 'set' checkbox. Editing anything sets everything, but you can unset them.

  whole widget has a 'clear' which zeros and unsets all

  rows are color-picker; slider; choice

  it would be nice to be able to set rx, ry, zoom on a little stage widget

  a settings element is selectable. on hover, all affected attrs light up as a hint. If they're offscreen, show a '5 more...' overlay on hover

effect editor

  one editor with an editable-resource choice. save null as new effect; edit existing; page has a session name, which could almost be automatic except it might be hard to rejoin your last anonymous session

  easy to pick groups or classes of lights to edit, maybe with hotkeys ('show just quantums')

  some lights should default to hidden or last

  allow multiselect

  copy from one dev to another(s). copy just one attr?

  line up devices in spreadsheet rows or cols to more easily see which attrs are different

  when editing a slider, show hints of what other devs are set to, and maybe even snap to those values

  this is a 'settings' editor. how does it deal with effect code?

  it would be nice to take 1 note in a song and quickly fork its effect for a custom edit, or even express overrides somehow

light9-color-picker

  try only waking on drag (not hover), but the big rainbow is offset so your drag starts at the current value

  skew the gradient even more towards desaturated colors. Currently, the lower half is almost all the same effect

timeline

  need to see autostop

  snap to autostop and to other curve points and to markers

  hotkeys to add markers

  note attrs box should let you swap the effect but not unlink/rename it

  progressive reveal of UI as note grows: first, effect. then add note controls, then add l9-effect-scale

  fade adjusters are very useful, but just grabbing the fade line should be enough. But don't let dragging the whole note move the origin, since that's way too easy to hit accidentally

  pack the rows down to the fewest required; don't waste 6 rows of space all the time

  more note operations:

    copy note, paste it repeatedly at multiple markers

    split note (to clear out a section for another effect, or to more easily say 'note ends here')

    adjust fade about its center

    animate scale at more points

    add more curves, like for rx,ry to do a follow spot

  take a few note effects and combine them into a new effect, like you would in KC

timeline internals

  syncedgraph -> diagram values -> diagram screen layout

  DV is just all the value() calls precomputed and maintained across patches, for performance

  DSL is the positions of everything, after zooming, after adjuster creation and layout

  inner-attrs probably don't need anything special, since we can always 

KC rewrite

  drop qwerty controls

  the row that is mapped to hardware sliders needs to stick over restarts (and work when no browser is open, too)

  have effectsequencer run the effects; don't do it in the KC process (which wasn't reloading right anyway)

effects

  need more easy to use random primitives, or maybe i just always forget about noise()

  given some settings, have easy canned effects to add: chase, blink, hue rotate, offset lights (maybe just during fade-in)

effectsequencer

  drop sticky attributes for lights that are on- they lead to errors with unset values. Ok to be sticky when the light is off, but if it turns on with a setting at 0, you have to go to 0. Also, ES needs to look aheead at coming notes and plan how values change before the light is turned on

collector

  drop the remap system and do it as a UI thing instead, where slider ranges are remapped on screen but you can see their ranges are adjusted. Then we don't need other translations later. I'm not sure if this will make trouble once we can copy rx,ry values between devices and they're not aligned. But if it does, do the remap at paste time.
