So far so good, no crashes yet.
However, I've always had an issue with the responsiveness of scrolling. Especially since I use freewheel scrolling without detents, so once I start a significant scroll, I could be waiting for half a minute until it's finished scrolling. Even just scrolling single steps, if there's a lot of stuff to paint, it can take up to about a second, and it seems to be completely synchronous/blocking on the UI thread. My PC isn't the most powerful these days (2x 4-core Xeon 3.3GHz, no HT) but I'm sure the paint routine can be improved, perhaps asynchronously; scroll, bitblt, enqueue the full redraw the later? I made a screen recording that I'll link to once it's uploaded.

Secondly, composite waveforms don't behave quite how I expect. When I have take lanes open, if I have multiple clips with interleaved audio, and I have sections of one clip muted, this ghosts the waveform of the other clip in the composite waveform. When take lanes are closed, it only shows the topmost clip, which I suppose makes sense for editing, but it's not reflective of the audio. Picture attached.
Other than, well done! Super pleased with the introduction of ProChannel module presets! (But would love some copypasta so I don't have to save temporary presets. ? )
