Ah, if you guys mean simple
location syncing, that works a lot better for me in Marvin 3 than in Marvin 2. iCloud is used in Marvin 3, as opposed to Dropbox in Marvin 2. In Marvin 3, just tap the button in the right corner of the bottom toolbar, and that will give you a very nice listing of possible locations to sync to. That's a lot more elegant solution, to me, than the rather haphazard method of location syncing in Marvin 2, and I'm also landing in the proper locations now in Marvin 3, unlike (frequently) in Marvin 2.
