I started with an idea for organizing multiple projects, but added a few features that might be useful for other users ( eg: file uploads for designers wanting to organize images ). You can create spaces for different categories or projects, add notes, files and bookmarks and tag them or search for keywords to find everything from one place.
I launched on ProductHunt yesterday ( https://www.producthunt.com/posts/webfolder ) and got 27 signups. On to get more users !
