Well OK, but for instance, I converted .capx to a project and I got X number of images for every frame per sprite named like 001, 002, 003 and so on. This is unusable to me instead of to have all frames of a sprite in one image. Maybe I need to make a new project from the start?
Anyway I don't see why should be a problem if you move or rename folders of objects. A user is responsible for that and must be informed to not change names of files and folder structure if want to update them. In that case there can be displayed a message "Error, can't find image to reload it".
I'm just suggesting some improvements to things I found as a difficulties to me in a work with C2. At least, "Delete all frames" option would be also welcome.
