I find this Github integration very finicky… Sometimes when I add new GitHub Repository via Owner/Name/Branch and then do a ‘Update from Repo’ it doesn’t show anything in the ‘New (only in GitHub)’ column even though I can see items when browsing on Github. Other times it show files I can add but when I select them and add them it acts like it worked but they don’t show up in My Devices/My SmartApps. I often have to resort to copying the code manually which negates the value of using github.
I have a degree in computer science and have to say that unless this platform becomes much for user friendly I think it never become main stream. Why aren’t people publishing their smart apps to the ‘Marketplace’ which would make accessing them much easier?
