While we update our documentation I will use this discussion to provide details about the possible icons:
Following icons are shown when a project is under source control
- “pencil” - indicates modified files
- “plus” - indicates added files
- “branch” - indicates file is present on repo
Following icons are related to file properties. I named the file with the indicated property. Also if you right click on a file you get to see the contextual menu with icons and this is a good indication of the available options.
Hope this helps,
