Ability to add new sections?

Hi,

I’m enjoying using ManagerManager but I’m curious why I can add new tabs and move fields into them, but not add new sections in the page? I’m finding that end users forget to look at the tabs, so grouping my Template Variables into sections on the page would be more usable.

I thought this had been present in one of the early releases, or maybe I’d added it myself! I’m curious if there’s a reason it’s not present or been removed/left out - performance perhaps?
