Advanced Group Rights : Show/Hide sections
Much like the same functions as many forums
(including this I would asume) can do but many not SO advanced.
To have the option to give the different custommer you create different rights of what they can do/not do but more importantly see and not see. This is a constant issue I run into as a wholeseller since I work B2B.
Basicly all ecommercesystems just gives me the option to asign discount to each group, but not much else.
I need to be able to hide recommended prices and other information for noncustommers (as in MY custommers custommers.

).
So ...
Some type of section under the groupcreation that lists various functions in the Tomato that you can tag on/off + a section for each individual product/category. Think/look on Facebooks
Privacy Settings and you get an better idea what I mean.
