Created attachment 1426 [details] Extended filter dialog Some parts of Claws-Mail UI do not properly adapt to increased font size (e.g. for high-DPI/retina systems). Sample case: Extended filter dialog for message list Most dialogs start rather small (default size expressed in pixels instead of relative to font size?) and need to be resized before being usable. All widget/window sizes should be proportional to font size so their intended content has enough space, though not exceeding monitor size.
