If the new version of the iteration status page is causing you productivity problems or is too slow to manage during fast-moving stand-ups, I have a suggestion for you. Create a custom page and add the app "Iteration Tracking"
For you aficionados of "expand all", yep that's there too.
Are you a column junkie that had to make information sacrifices to fit into the now limited number of allowed columns, well the custom app does not have this limitation.
Are you using tags to cycle through team members during stand-ups? If so, this is the old tags drop-down that is more responsive and quicker to use as people talk.
Did you miss being able to click the letter square for a status in schedule state and have it accept that status without presenting a drop-down to make your choice? Yep, that's back too.
Basically, everything is back as it was on the old iteration status page with the exception of the iteration metrics bar that is unique to that page.
Need the option to split a story without going into that story? it's back now with the gear icon on the user story line.
I hope this helps if you have been struggling over the last few weeks.
