It would be nice to have a couple simple variable prompt templates. For example sometimes we are using our variables for boolean values yet we have this giant text field that easily confuses people. It would be nice to have a simple ui way to make choice selections (at a minimum) so that we could have it be true or false without having the user input true or false at build time.
Thanks for your suggestion!
I have added it to UserVoice for you here:
