Pro sites

I am creating a pro site and was wondering about a couple of features.

1. In the feature table can you add titles for instance
title
feature
feature
feature
title
feature
feature

2. Is there an option to restrict users for pro site subsites as I would like to create subscriptions based on this

3. In the module section, there is premium plugins which allows me to select the min level and automatically activate plugins in the prosite subscribers account and there is the premium plugin manager which allows me to select specific levels for plugins

Is there a way to select specific levels for plugins and automatically activate them?
