Allow for more rapid boards to be displayed in the Agile dropdown menu

With the recent change to GH rapid boards, you now cannot switch between boards by clicking on the name of the current board and navigating to a new one. Instead, you have to click the arrow by "Agile". This is OK, but the list of boards now only shows your 5 most recent boards, whereas in the old model, you could see many more boards (it might have been all of them). We have many boards and frequently flip between them, so having to click on Agile, then "more", and then find your board and click on it is a little tedious. There is plenty of real estate to allow many more boards to be displayed in the Agile dropdown. I'd like to see at least my last 10 boards, if not 20 or more.
