Storyboard Feature Suggestions and Ideas

Would be nice to open in the IDE's browser e.g. Eclipse, IntelliJ
Themeable - i.e. different skins - just switch around a set of files .css & images
Custom Items can be created - loaded via the XML. Item editor - just input as HTML.
Tracking XML
What about concurrent use? Does it update in realtime? What about overwriting over ppl's stuff (conflicts)?
Flip a card - have something on the back e.g. pair history / detailed tracking info.
Maybe not auto-save - but a source control model. i.e. update & commit
Zooming - via. font & image size i.e. every item is zoomable
Zooming - Or just diffferent views - one big high level and one close up.
Tracking Data - which pair on which tasks on which day & how much was done
Revisions Tracking - Which user modified card X and why?
Printing - Print every card quickly & easily. On card format or normal page format. (maybe specific card printer)
Burn-up / down charts
Velocity tracking
Exportable - stories, tracking, charts, calendars. Formats: XML, CSV.
Copy & Move cards between boards

Possible minimum requirements
