Unfortunately, I do not have any more time to put into the VSE Reworked Project, and I do not know how to submit patches to Blender, so I’ve written to the maintainer of the VSE and suggested that he or anyone else can use the code if it is found to be useful.
It includes 23 new functions, 15 existing functions added to the menus, a full reworking of the menus and also a reworking of the VSE panels into 2.80 style.
