Quick Switch Project includes entries for all recent projects, whether or not the recent project was deleted. I’ve used and deleted a bunch of projects but using Quick Switch Project was a pain because I had to navigate through all the deleted projects to open the ones I’m currently working on–the dirty fix to this is to go to Project -> Open Recent -> Clear Items, but that includes deleting entries of projects that exists (not deleted) as well, meaning that to clear deleted project entries this way, I would have to create and save the projects that I want after executing Clear Items because Clear Items deletes all projects, whether deleted or not.
Why not have a setting for Sublime Text that keeps track of all projects in a specified folder and then Open Switch Project shows all the projects that exist in this folder? Therefore, deleted projects will not show up in Open Switch Project while saved ones will.
