Organizing/Moving Assets is a pain

I have a mid-sized project with some thousand items and want to move the 12 content folders into a single main folder.
This doesn’t work, even with applying Redirectors, there’s always some file not copied or a missing reference.

I like to suggest to go back to the simple relative scheme, where the relations are defined by the hierarchy of the file system.
This way, we could migrate more easily and in any subfolder we like and the filesystem cleanup after moving folders would be obsolete.

Migration into a plugin content folder leads also to missing references as can be checked with the Reference Viewer.
