I couldn't find a thread for comments on the new (beta) dashboard, so here's one suggestion:
The old one had the cost of the plan level shown for what "level" your current usage puts you into. That's no longer shown on the beta dashboard (I have to go to the "Plans" page to cross-reference what the pricing should be). Would like to see that on the dashboard again.
Otherwise I really like the new dashboard!! Especially the "per line" alerts plus the ability to "shut off" texts and data if that line exceeds a preset amount. I don't see an immediate need for it (it's a business account), but it's nice that it's there and would probably be wonderful for a family with kids.
