As for complications that may arise from account sharing, it doesn't really change much since people do it anyway, regardless of where the key binds are saved. People who do share accounts do so at their own risk, as with any type of online account sharing. In a game where alternate characters of different classes and levels are a necessity to obtain many things, mainly monster cards and item farming, sharing accounts is the ideal alternative to creating over 20 characters and leveling them up.
This is more of a convenience thing rather than a necessity, but it would be nice if it could be implemented. If security of the key bindings is an issue (perhaps hacking it so that pressing a certain key results in a macro, if that's even possible), please consider making separate bindings per character per different IP. If this ever becomes a memory issue, unused bindings for over 30 days can just be deleted and reset to default.
Oh, and please let us change the screenshot button. I don't want to use the default screenshot button, and I would like to use it for taking a higher quality ss with a different program.
