I think that the custom medals of TUS are beautiful and sometimes it's not possible to see their details, because they are too small. It would be nice to be able to click on them to expand the image or see the original big one with all the details. The same goes for Scheme icons. The only concern about this idea is that maybe this will occupy too much space of the TUS server, but since the activity is not as big as it used to be and now I believe that people grew up, have a job and can help donating and contributing to TUS, I think this would be cool. People would appreciate much more the custom medals they have and will struggle much more to earn more custom medals, and people will try to make more custom medals, because they are cool.
