is there a way to automatically detect alts during upload without having "Alt" in the notes? maybe make the highest lvl toon the auto main and all the rest listed under alts.

It's been suggested to me before to update like that on character updates, and I have some ideas on that matter. I'm releasing 1.3 now and I'll look into what functionality I want to add for 1.4 over the coming 1-2 weeks.

Any update on the progress of this becoming a reality?

I've been working on the admin control panel for R1.8, sorry.
