I mostly use photoshop to remove objects from photos, place in images rendered with blender and retouch them to look like they were part of the photo, I think Darktabke doesn’t have tools similar to healing brush and patch tools in photoshop. Although photoshop is working perfectly so far, it would be nice to find a native application that is up to the task. I haven’t really tried hard to look for linux alternative that can do that.

EDIT:

Wait, I just looked into it and there are such tools! Thank you for suggestion! I might try it!
