That works fine for the Mac, but I'm wanting to share my Packages directory with Windows machines as well (so snippets and whatnot just work across various machines). It looks like the --data command line option no longer exists in ST2 (is that the case?), so I've moved to keeping the portable build in my Dropbox and symlinking my Mac data directories appropriately.
The one hitch in this is that Windows doesn't seem to be happy letting me set an exe in Dropbox to be the default handler for a file type, so I can't double-click on a file in explorer and have it open.
Does anybody know a better way to have ST2 use a different data directory?
