@Jeannie____ well if you are “fed up” with gtk DE’s, dont want to use KDE, or lxqt, or lxde (which you can install composters on to make it fully featured) and want a fully featured DE I do not think there is anything out there for you at least yet. maybe try out Deepin Desktop Environment before you call it quits and may i ask why exactly you hate GTK just for reasons I am starting to think this is a troll post/ maybe we can work to fix the issues you’re having with gtk
GTK3 theming is a disaster, especially when you need to use dark themes. Using dark themes causes problems in a lot of appplications, you’ll end up with white text on white background in text boxes if you use something else than the only one (adwaita) theme that’s hardcoded in the toolkit, which renders these applications useless.
Besides that, I really dislike the damned confusing client side decorations of GTK3, I want a proper menu at the top of my windows, not some burger buttons and other smartphone-like usability aiming at small sized displays, I can’t stand the f*cking cryptic dconf? gconf? ( dunno how it’s called nowadays, maybe it was renamed, again ) settings which buries things sometimes deep in it’s hierarchy.
GTK3 simply is not usable outside Gnome3 anymore, as it’s closely tied to Gnome by the people who develop both ( and have a bad influence on other non Gnome3 DEs that way).
GTK3 means: The GTK3 dev’s way or the highway. In case of GTK3, I chose the highway.
And before someone accuses me of GTK3 trolling or bashing now: I just answered the question why I hate GTK3. This GTK3 hate is based on my own experiences made by using GTK DEs that evolved from GTK2 to GTK3 ( MATE) and by occasionally trying Gnome 3 from Version 3,0 on over years.
