date/time indication of last sync for each folder.

When folders are not set up to be synced on a schedule, they may not be up to date with the server.  I suspect that the all mail folder shows the contents unique to aquamail but that may not be the current situation on gmail.  One can always sync manually.  Is there a way to see when the last manual sync occured, say in the folder list.  Synchronizing all the non synchronized folders probably would be good if one is trying to search for an older email with say a serial number on it or some such.
I guess one could just synchronize the all mail folder and search from there.  Any thoughts?

There is an indication of last sync time, it's disabled by default -- but applies at the account level. Tracking it per folder is technically possible, but I'm concerned about overloading the UI too much.

As far as "all mail" being unique to my app or not -- if this is Gmail, its "[Gmail]/All mail" is independent of my app.
