Its a shame this is what stagnates linux. I am not sure what I am going to do had alot dark themed programs
that were not displaying properly so I either deleted them or took them out of menu.
This lenovo is not my main machine and solus runs great on it.
But I hate say I am going have to think alot on setting up a main linux machine and how to handle it.
(Dunno just draining my cells..)
olivir well that killed the gnome itch ive been having recently (plasma)
WetGeek I've even given some thought to using it instead of Dolphin on Plasma
I did give Caja a try just now. It installed just fine, but did not show up in the menu. That's happened to me before, and rebooting fixed it, but not this time. I'm curious enough to try it but not curious enough to learn how to use a menu editor to add it. Looks like Dolphin gets to keep its job here, after all. 
WetGeek It looks like Caja is only set to show up on GTK-based desktops in its .desktop file. I'm not even sure how that key works with KDE.
I think vanilla dark Adwaita looks fine. I understand that the issue is underlying incompatibilities with libadwaita etc but the theme itself is fine to me. If I could just use that all over it'd be good don't need fancy themes, as long as it looks coherent and functions.
Isn't there a way to just "use whatever GNOME is using" for theme related stuff, to eliminate theming woes going forward?
[deleted] Well, there is the adw-gtk3 project which aims to, as much as possible, follow the libadwaita style, so you can have a unified theme for your gtk3 and gtk4/libadwaita apps.
I've been thinking about packaging that, together with Gradience, to make it easier to get a coherent experience, if you so choose.
Can somebody check if copyq respects the dark theme, because no matter what on my system it is WHITE after the last update.
@presianbg @sangheeta could you please install this Qt6 plugin:
sudo eopkg it https://packages.getsol.us/unstable/q/qt6gtk2/qt6gtk2-0.2-1-1-x86_64.eopkg
This will resolve your theme issue with copyq and with all other qt6 apps too.

The Plasma menu editor is very very easy to use, believe me. I don't know if it would be possible to add Caja, but you can try.

I believe you. I went through all the right motions, I'm pretty sure, but Caja didn't show up in my System sub-menu, or in the Applications sub-menu. I even rebooted, just to make sure I hadn't left out a step. I suspect that kmenueditor must limit itself to installing KDE applications. Thanks for the suggestion, though. I learned something about my favorite DE, and it was well worth a try.

I have the same issue with nautilus, calculator and calendar. Very much dislike it and that themes aren't followed by apps any more is, sorry Solus (which I love), a no-go.

So does just about everyone else using a DE that is tied to the Gnome stack. The changes have been coming for months and months, and have been well documented, but app developers did not adjust in a timely manner. Nothing new. Linux has experienced disruptions of this type for as long a I have been using it. It will work its way out, eventually.
