Double rows of pinboards; I have so many I have to scroll too much to find the ones I need

I love Paste, and I use it so much that I now have 19 pinboards (and growing), and often I have to scroll sideways to find the right pinboard. Could you enable Paste to display two rows of pinboards when the Paste bar pops up? Either that, or find some other way of displaying more pinboards. I have come to realize that a huge proportion of what I do revolves around sharing the same pool of information, but having pinboards spread sideways in one row just isn’t efficient anymore.
