Add more directory options for opening/importing files.
The ultimate support-any-sync-method option for power users.
For example, I use Syncthing to sync my GnuCash XML data. On Android, this ends up in a location like /storage/emulated/0/sync/gnucash.
Whether using Syncthing or any other custom method, allowing GnuCash to open files from any custom location could support any syncing method (or at least I naively think so).

When importing accounts, you can import from anywhere. If you have a file provide (e.g. OI File Manager), you should be able to select your file from your SD card.
GnuCash Android does not do auto-sync for you though. You will need to import it yourself.
