Custom themes and bootstrap

[listy]

Finally, as you can see with the TACTIC community site, we are hoping to include a major a revamp of the TACTIC index / admin index using bootstrap in TACTIC 4.8. We are still in the discovery phase, but it is looking promising.

Can we take a little look at this super secret new admin index with bootstrap in TACTIC 4.8? 
If its look and feel will satisfy all of us, may be it's don't worth doing custom theming
