I really like the interface on this app, and the fact that I can create custom brainstorming sets based on existing ones (or from scratch). Very well thought-out. My only complaint is this:
If i want to randomly create 20 characters with the Character Builder, in order to save each one, I have to either Tweet, post on Facebook, or email every combination. I would very much prefer to add the randomized combos to a list that I can email all at once (or even just add to the paste buffer). As it is, I have to use this in combination with a computer, or a pen and paper to collect a set of character (or other type) prompts. Im certainly not going to bombard my twitter followers with the output of this app twenty times in a row.
Please consider making it possible to accumulate a list of brainstormed combinations.
