1) yes
2) I think that you CAN replace existing trophies ( or maybe only medals, I’m not quite sure at the moment, military duty, I’m visiting the community with my smartphone, if it’s only for medals I’ll make sure that it’s implemented for trophies too in the next release )
3) no, that’s not possible yet, but it’s implemented for the next release.
4) that’s out of my Control but with the new upcoming criteria and expression features in the next major release you’ll be able to do literally anything with this app
