[Suggestion] do not create new titles or color clip or others on "Stabilized" folder.
This happens a lot to me, after using a stabilization usually the focus remain on the "stabilized" folder, and when i add a new title-clip/color-clip or others they go in the "stabilized" folder, can be nice if kdenlive can understand that the target folder is a "internal use" folder and create new clips outside it.
inserting an image is doing the right thing, the JPG is placed outside the folder.
