Here are some bugs and other thoughts.

BUG. The "Release at end" option does not work for the scenes. When this option is deselected, the scene is set to pause mode but DMX data is still sent to the fixture. It releases the channels and it must not. This is important when using moving spots, where the beam must stay lit after a movement, until the scene is unpaused.
(example attached - just remove the dummy ".zip" extension).

BUG. The strobe effect should display in 2D view for all values. This had been reported before with a sample file. A solution would be to begin to simulate the strobe at a lower rate, so that greater values are still visible. Or by using a non-linear scale.

IMPROVEMENT (important). In some cases where precision is needed, it's very convenient to increment or decrement DMX values by 1 with the keyboard arrow keys. A classical example is to align a very narrow beam to a distant target with pan/tilt at 16-bit resolution.
But there is no way (as far as I know) to select a channel fader without clicking on it or on the fader track. Doing this, the value is automatically changed, depending on where it has been clicked, and the current value is lost.
The idea is that any channel can be selected by a left-click on its icon at the top and/or on its number at the bottom, so that the arrow keys can make it move.

IMPROVEMENT. It would be more convenient if the keyboard arrow keys were set to repeat mode without having to hold the Alt key. This would be handy for scrolling through the channel faders and for setting DMX values on the faders, quickly and easily.
**edit May 9, 2016** : in my opinion, no longer needed (with the arrow keys above the faders and below the faders, it's enough).

IMPROVEMENT (minor). When right-clicking on a fader icon, presets are displayed in a pop-up. If a channel has no preset (e.g. RGB color, pan, tilt, ...), the pop-up should maybe not display the "Map to DMX in / Map to MIDI in) menu. It's not that important but simply better that way, in my opinion.
