SUMMARY

KDE Dolphin has always been my favourite file manager, as a power user who loves making it do more & more.  However, configuration's services add-ons sometimes break dolphin permanently and can't be removed, so there needs to be quality/version control.  Some aren't consistent with language, so I installed some that had English titles but Spanish (I don't speak it) everywhere else.  Some had the effect of permanently disabling/hiding official Dolphin services.  Some were duplicates you can't really tell which is official or not or remove some.  Additionally, there are services going back to KDE3 in the list (but dolphin wasn't even in KDE3?)  There really needs to be quality and version control: testing the add-on services, making sure ones that break the dolphin system aren't listed until fixed, and making it clear you get add-on services for the correct KDE version: not several versions ago, because I tried installing dozes that were old and they couldn't even install.

For now, is there any way to reset dolphin services to defaults without removing ~/.kde and most of (other than a few non-KDE things I use) ~/.config & ~/.local and reinstalling KDE?


STEPS TO REPRODUCE
1. Install as many neat-sounding services as you can.
2. Look in the service menu as a user.
3. See some broken, some system ones broken/moved/missing ('crash') and ones in other languages.

OBSERVED RESULT

Lots of breakage.

EXPECTED RESULT

Shouldn't break things, and should be allowed to remove unofficial ones and/or  restore defaults.
