Step 3. Describe the issue

Logs

I am aware of the existence of shell.json, but it only allows you to change quickshell configurations. If I want to add a function myself. Where can I find the configs of quickshell itself?

Sorry for English, I'm using a translator.

Reminder

• I agree that it's usually impossible for others to help me without my logs.
