Apologies if this has been addressed already; I did a search and couldn’t find anything. In my understanding, “flexible space” in the tool bar is supposed to force a large space between items, so that some items can be left-justified, centered, right-justified, etc. It doesn’t do that for me. (See screenshot.) It seems to me it’s a bug though possibly I’m doing something wrong?
Flexible space is only useful if the toolbar items do not yet use the complete toolbar width. But in case of main windows the search field uses already (most of) the available space.
