Sometimes, you're not sure which characters you have, and scrolling through all of them can be fiddly at times.
It's also fiddly to find which talismans are equipped on which characters, when you want to swap them.

Being able to export your team roster to a file, say a .csv text file, that you can then use in something like OpenOffice Calc or similar, would be pretty neat, and make finding which characters you have, and what talismans they have equipped, so much easier.
