Suggestion for zeta and omicron upgrade badges

I would like to suggest that you guys add small purple and grey badges to the character icons in the Character screen when the toon has a zeta or omicron upgrade available, respectively. These would replace the generic red badge.

For example, this could help a lot when a player gets a new omicron or zeta, and wants to easily see what his upgrade options are. As it is now, the player is forced to select every toon with a red badge and see if it's a zeta or omicron that can be applied.

Even better, you could also add a filter for "zeta/omicron upgrade available" so that we can see only toons with an upgrade available.

Thanks for listening.
