i'm thinking about adding Properties.. context menu:

that would open separate proper properties window,
where you could manage things related to that project:

• Secret Project *if you dont want to show this project in the list (during streaming, screen shots etc), this could hide the project, or maybe just scramble the name and path
• Clear Library Folder
• Shows more project info and details Size in disk, Current platform...
• command line arguments editor (select args from ready list?)
• see list of packages and assets in the project
• project thumbnail (app icon, or manually selected image)
• project tags (so that can search by tag: like "work", "game", "vr")
• quick view of files and folders in the project (with search would be nice, if you are looking specific project that contained something)
