Not a long time ago, I prefer WPS Office to LibreOffice, since I was used to Microsoft Office-like ribbon interface than traditional menus. But now, to stay true to my use of open-source software, I switched to LibreOffice.
So far so good, but LibreOffice’s file dialog sucks. It takes time to move to other folders, and GTK bookmarks (which I use a lot) are nowhere to be seen.
I can’t find the fix on the internet, but it’s easy. To use the more familiar GTK file dialog, go to Tools>Options>LibreOffice>General, and untick ‘Use LibreOffice dialogs’.
