Ability to have templates in notes. This is useful for when you are doing organization of things like Names / Addresses ,etc. You can build a template to be filled out using Tables and then when a thought is created as a child of a thought it would inherit that text template.
As a workaround I create thoughts titled Template, [Template Type]. I set the notes, color, thought type and tags as needed. Then when I need to create a thought using this template I activate it, choose ctr+shift+d (shortcut for duplicating). This duplicates the thought. I then Shift + activate it's parent to do a thought move and change the name to what I want.
It actually works pretty well. See here for a better description: http://webbrain.com/u/12BU

I like this for the look and feel of a note or type of notes. That is choose the styling of titles, background etc.
The structure of the text I think is better served by: http://thebrain.uservoice.com/forums/4597-thebrain/suggestions/70182-node-types-with-structured-meta-data-?ref=title
This way you can have more structure across the brain and do things like search addresses across the brain.

Instead of thoughts inheriting the note template I would prefer a possibility to create note templates for thought types, or a menu in the note tool window, where you could open a template.
Hm.... This seems to have a lot going for it, but it assumes that Notes are more useful that a basic repository primarily for text. If you allow that assumption, then all sorts of possibilities arise. Forms, data merging...
Before I vote on this one I'd like to see which way structured data is going to be implemented.
