hello, I just started using Mypaint, and found it's really a nice
application, I like it very much.
I have a little suggestion: I use to import reference images or sketches
from different files, and I found that sometimes it would be useful to
have the possibility to re-position the imported layers, to match an
existing drawing or for similar purposes, so I added a quick and a bit
dirty way of doing it (I just had a look and got lost in the code, so
there are probably far better ways to do it, bu it's just a suggestion)
basically I would add the possibility to move a layer using
<control><shift> and arrow keys, and proportionally to zoom level, so
you can zoom in for fine tuning of displacement.
I include a patch, and I would love to have your suggestions and tips if
you think there are smarter and better way of doing it.
best to all, and thanks for your nice and impressive work
