In addition to what I said above - the patch comes with two small side-effects - The size of the content in the tab is constant over the tabs, so that even a page with not very many settings will show a scrollbar, even if it only makes it possible to scroll in empty space from below.

I have made a patch for this, that add scrollbars to scroll up and down in the settings. This adds the need to set a default window size, which I have set to 700 x 500, which seems fine. Tested on a relatively low-resolution machine (1366 x 768), where it seems to work fine for me.

Related, the tab formatting (mixed first one tab and then space), as in lines 131 to 137 of src/icons.c _really_ causes headaches.
