Very helpful Rated 5 out of 5 stars

I like this Addon! Solves a lot of tab hassle for me. A slightly more detailed manual would be cool ('Aging amount per step' - not very clear to me what it does from just looking at the name).

to Positive Attitude: with regard to Coloring, it may be helpful to use Tab Kit's color labels (as opposed to fully colored tabs: in Tab Kit go Options/Tabs/Tab Coloring section, and pick: 'Color labels by group and tabs if highlighted' from that drop-down menu). Thus you can combine the grace of Aging Tab's "fading" effect and Tab Kit's coloring. In all, Tab Kit still works fine for me: domain grouping/collapsing as usual. Beyond that, I think Tab Kit integration with Aging Tabs would be cumbersome, imho.
