However, it is super hard to find that button, it only appears when you hover over the tab in the statistics panel that is currently open. I also still think there is potential for the analysis board to be larger, because the statistics don't collapse entirely, but I guess it's good enough.
They've added these weird statistics below the analysis board, and this has reduced the size of the analysis board. I would like to remove these statistics so that my analysis board is larger.
