I tend to have the tree disabled unless I explicitly need it -- I tend to get around by way of location typing rather than tree navigating. Unfortunately, when doing so I do not have access to the catalog. I'd love to see (a)a keyboard shortcut to toggle the tree panel off/on (b) a means of accessing the catalog without the tree being enabled -- either through the favorites menu or just the ability to enable the catalog independent of the tree.
At any rate, with tree and info panel disabled, enabling the catalog causes the catalog to attempt to appear. Unfortunately, only a few pixels of it make it to the screen, as pictured.

Before, tree and info panel are hidden
