In proofreading mode, different categories of correction suggestions are shown at the bottom. Right of the category tabs there is a downward triangle to condense them and make more room for the text. However, this puts the handle to expand them again behind the floating buttons for copy, read, download, making it impossible to re-expand the corrections (actually, a few pixels of the hitbox of the upward triangle are still accessible, but that's obviously not the solution).

Button for expansion should remain visible. Either move the floating buttons around or the condense/expand ui element.
