Created attachment 196514 [details] Autofilter buttons vs UI buttons (LO 25.02 nightly) The down-arrow buttons we get when AutoFilter is in effect look "custom-drawn", and remind me of Windows 95 or even Windows 3.x down-arrow buttons. Be that as it may - they are certainly different than the buttons we see on combo-boxes, and the down-arrow is not even like the ones we see on toolbar menubuttons. It would be more visually pleasing if the buttons, and the down-arrows, looked like (or actually were) native widgets.
I'm not sure about the feasibility of using native widgets here, specially because of zoom levels. However I agree with you about the need to redesign this button... it feels old to me as well. I like the minimal design in Google Sheets.

Created attachment 198194 [details] AutoFilter dropdown in Google Sheets (In reply to BogdanB from comment #2) > Google Sheet dropdown mentioned by Rafael. Actually your screehshot shows a data validation dropdown in Google Sheets. I've just attached an example from Google Sheets where you have the AutoFilter dropdown. TBH I like them because they're clean and light on the eyes.
