Thanks! One of the things I'm trying to do design wise is eliminate/minimize pop up screens and multiple pages, etc. I want everything to accessible from one screen.

My plan is to add functionality--initially realtime collaboration--and then comments, tasks, assigned users, point/time tracking, etc. but make all of the features opt-in and customizable.

I consider this the real minimum viable product. Just a list of items. Priority represented by position in a list. Status respresented by WHICH list. An unobtrusive backlog. An accessible archive. I want people to be able to use it at this level of simplicity a year from now.
