I've noticed that while drawing a selection with the marquee tool coming from PS I was expecting modifier keys to work, such as holding Space to move selection while drawing, holding Alt for center to bounds drawing. Also missing were cursor cues to the action, whereas the cursor never shows a plus sign if adding or minus if subtracting, x for intersection, etc. Are these features planned?
On a side note, the software as is is quite impressive, the native filetype crunched an 80mb PSD file to 17 while retaining quality. I mainly do comic book coloring with PS and most features are there, save perhaps a few like processing grayscale to bitmap for the line art, but it looks like I could migrate. The UI is snappy, we like it.
