In our line of work as an MSP we regularly switch between passwords which are client specific and those which are product specific, so it would be helpful if we could pin certain shortcuts to the top of the list (along with e.g. ‘All items’) and then have the leftmost list scroll from below this, so that we could (In my example) scroll the list down to the specific client and then click between the client collection and the pinned product collection without scrolling back and forth.
For an example of what I am describing, look at the ‘Favourites’ section above the mailbox/folder list in Outlook.
