In my project I use a lot of libraries and I typically bake them into my source to avoid version conflicts and to ensure that anyone else with the source doesn't need to go on a hunt to install all the required libraries.

The issue I have is that occasionally BYOND decides it wants to expand all of those library folders, cluttering up my project's file browser. It'd be nice if there was a way to lock folders from being expanded, and possibly lock them from being modified or searched as well.
