On a 4k screen set to 250% the RESET button in the Filter by Category panel and also the
Filter by Folder panel is too small and thus easy to miss. (See screen shot)
Request is for a larger button or at least a different, more contrasting color.
More convenient would be, I find, to have the button on top.
