I really have no other wishes for Gimp aside from stability and performance:
- I learned the Gimp hotkeys first
- I know the menu structure around filters and so on is weird compared to PS, but I know it
- I like selecting, zooming and scrolling better in Gimp, somehow I have the feeling of more control and find it easier to make something pixel-perfect while getting sent non pixel-perfect .psds
- I like the old multi-window interface, even though it took me some time in the beginning to grasp it
- the text tool is fixed now
Maybe the only thing, which sounds interesting to me are the advanced and non-destructive layer options and transformations (or whatever these features are called in PS), but then again: I know my way around Gimp and if the PS layers were fully supported it would already be fine for me.
Edit: Have seen another comment about non-destructive editing and found out, that it is on the roadmap for 3.2 after GTK3 in 3.0. So my hopes are that this way the PS counterparts will be supported, too.
