Description Giovanni Santini 2025-11-30 08:52:44 UTC

SUMMARY
Currently, Day/Night tooling can only swap between full Plasma themes.
No granularity is available, thus one needs to modify the theme itself in order to change e.g. icon themes.

This issue is for requesting granular control as an alternative: after choosing the global theme, the user then has the option to choose cursor, icon theme and so on.

This is already possible with 3rd party apps like Koi.

STEPS TO REPRODUCE
1. Use the Day/Night feature.

OBSERVED RESULT
The whole global theme is swapped.

EXPECTED RESULT
Granular control over the swapped components.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version:

Currently on phone, will attaching additional info when I am back to the PC.

And because the whole global theme is swapped, even the window decorations are lost!

Even for just switching between Breeze Light and Breeze Dark.
I'm really tired having to go the System Settings to re-set the custom window decorations (Klassy) that I use, twice a day or more if I restart the computer!

This is out of scope. It will result in an incredibly messy UX to handle a solved problem.

You might find lookandfeelexplorer from plasma-sdk has what you need to create a new lnf.

Comment 4 Giovanni Santini 2025-12-03 14:52:23 UTC

Even though you mention UX might be tricky, the Global Theme Explorer does not really solve the issue, since it is not clear how to use it.
