While looking through the Atom API I found that you can do some settings to the current editor that wont effect the others or the atom settings, namely soft tabs, soft wrap and tab length. So I added that into the Project Manager, so now you can add a settings object on each project, or just the projects you want different settings on.
'title': 'Project Manager'
'setSoftTabs': true # Enable or disable soft tabs
'setSoftWrap': true # Enable or disable soft wrap
'setTabLength': 2 # Set the on-screen length of tab characters
Normally I test all updates on my home and work computer before publishing the update, but I wont be at work for a couple of days so I have just tested it on one computer, so please let me know if you find any bugs
