Busy with a Bootstrap 5 project and suddenly I have pinekit.css in Google Chrome Inspector.
For the moment I have no time to find out the nice things about Pinekit, so I want to exclude them, how?
Solved it.
In Pinegrow go to the Styles panel.
Then click Stylesheets
Then Add & Manage (goes to the Stylesheets manager)
Then I found PineKit… from here you click detach from…
Or from the main menu directly
File → Manage Stylesheets
