Un-Deletable KWin Scripts

I am using plasmashell –version plasmashell 6.3.6

I have navigated to System Settings > Window Management > KWin Scripts.

Bug 1]
On the right hand side of the screen, there are a list of pre-installed scripts which are not deletable (Desktop Change OSD, Minimize All, Synchronize Skip Switcher with Taskbar, Video Wall).

[Critical] Bug 2]
I proceded to click “Get New…” in the top right corner and installed software called “Krohnkite”. It appeared in the KWin Scripts section. I have decided I do not want to use this software, and now it cannot be removed from the machine – the trash can is greyed out.

the canned ones cannot be delete, but you can disable them.

scripts added via the get new button are easiest to delete using the same process.

in the get new dialog you can sort by installed and delete anything you have added yourself.
