In various views, namely the product backlog and issue tracker, it's often frustrating not to view certain details (like which sprint or release an item belongs to). It would be helpful to be able to choose columns and sort based on any column.

The issue is exacerbated when you open a story or issue 3/4 of the way down the page to view its details and then get reset back to the top of the page after closing the modal... then you have to search for your place when doing things like making sure everything is in a Sprint or a Release. So you have to open each item, check it and disposition it, get reset to the top of the page, search for your place in the list, open the next item, etc...

This is also somewhat true of the planning board where you can't sort (or filter) and have to wade through resolved and completed issues.
