This comment reads like you've never actually tried Gnome with proper extensions (like arc menu and dash-to-panel), because those aren't even comparable in quality. I mean that when comparing to KDE as well.
I want to love XFCE, but whisker-menu doesn't support opening it on meta key release, which is baffling to me. Also the lack of night mode, which redshift is just throwing a random program into the mix. Which if you don't mind that, then you wouldn't have a problem with Gnome extensions in the first place.
Could you help me set whisker-menu to open on meta key release? This is default behavior on every other DE, yet seems completely unsupported on XFCE. It needs to explicitly be on key release, otherwise it breaks every single keyboard shortcut that relies on the meta key.
