As you may know, a Facebook group for the Video Sequencer Editor has recently been created. You can join here: https://www.facebook.com/groups/1981104845289453/ It is called: Video Editing in Blender Sequencer
One of the things we have been doing is collecting links to VSE add-ons in a now 7 pages long list. If you want to add your add-on to the list, then join the group and edit the Google document here: https://www.facebook.com/groups/1981104845289453/permalink/1988442054555732/
