| 3 widget to show all dmx channel levels and allow editing. levels might | |
| 4 not actually match what dmxserver is outputting. | |
| 5 | |
| 803 | 6 proposal for new focus and edit system: |
| 7 - rows can be selected | |
| 8 - the chan number or label can be used to select rows. dragging over rows brings all of them into or out of the current selection | |
| 9 - numbers drag up and down (like today) | |
| 10 - if you drag a number in a selected row, all the selected numbers change | |
| 11 - if you start dragging a number in an unselected row, your row becomes the new selection and then the edit works | |
| 12 | |
| 13 | |
| 14 proposal for new attribute system: | |
| 15 - we always want to plan some attributes for each light: where to center; what stage to cover; what color gel to apply; whether the light is burned out | |
| 16 - we have to stop packing these into the names. Names should be like 'b33' or 'blue3' or just '44'. maybe 'blacklight'. | |
