Explicitly specify parent plugin directory
I'm not super familiar with Sublime Text plugins, but some quick Googling pointed at /Users/<username>/Library/Application Support/Sublime Text 3/Packages/User/ (I'm on OSX).
Apparently if you git clone https://margo.sh/GoSublime into that directory, menu items show up but don't work, and margo never gets set up correctly. After banging my head against the wall for a while, I tried the same git clone up a directory, in /Users/<username>/Library/Application Support/Sublime Text 3/Packages, which immediately worked, and as a cherry on top created a GoSublime subdirectory of /Users/<username>/Library/Application Support/Sublime Text 3/Packages/User/ with the layout the rest of the docs implied.
This narrative is the long way of asking, any reason not to explicit put the correct plugin parent directory into https://margo.sh/b/migrate/ for each supported platform?
@astonm I'll rewrite it when I get a chance. I originally didn't want to include the explicit paths because I only use Linux.
