Need help finding a tool for managing all my files on a mac. It needs to work off the existing file system - not some proprietary storage solution (ie. Evernote). It needs to support rich text notes with full support for images and text formatting. It allows me to view different file types - and, ideally, edit them from within the app. I'd prefer it worked on local file system - rather than needing internet connection. I'm less concerned about synching. Any suggestions?
