back up settings

It would be nice, that we had the ability of making a back up once we finished setting all features, RSS... It would be helpful when we need, for instance, to change the ROM on the device we are running ttorrent (without using "backup´s apps")

This feature, should create a file that we can copy and save, and then import when the new installation has finished.

I don´t Know if this is already possible, but I could´t find it anywhere.
Thank you.
