Looks like the drivers all have an importUrl set in their definition now, so just clicking the "Import" button should populate the URL and allow you to grab and save the latest code without any manual copying and pasting on your part--just a lot of clicking if you have all the drivers on multiple hubs. 
For the app, once you paste the import URL into the "Import" button yourself once, it secretly saves that and will automatically populate the field in a similar fashion should you click "Import" again. Staff has commented here that they are looking for a way to unify this experience: Import Code from Website - Driver Code - #4 by chuck.schwer
The GitHub repo settings on ST still aren't working for me (doesn't see any files at all when I try HubitatCommunity / HubConnect / master), but I only have a few DTHs installed there, anyway.
