I understand an update is coming which may improve "talisman sorting".. so that might make this moot... (High hopes for such an update) but...

Currently cosmic talismans are grouped by default by their ability, then T level - color is largely irrelevant in terms of their sorting. This is a bit more muddled with character specific Cosmics because they tend to fall in the middle of everything else - after some augments but before others.

I, personally, think grouping cosmic talismans by color then T-level and making the ability the more irrelevant factor would be more useful.

If I know I pulled a T2 purple with the Blind augment it takes some time to swipe and find where the Blind augment(s) is/are. Even if I merely tap Purple T2s it can take some swipe-tap, swipe-tap, swipe-tap to find it. If cosmic talismans were grouped by color, I could merely swipe/jump to the purples then tap at T2s, which should all be next to each other.
