Can I create dockable dialog boxes in Python plugins?

in gimp 2.99 , Can I create dockable dialog using Python plugins?
Similar to the tool options、layes、brush dockable dialog and so on .

I think this is a very useful feature so that users can customize the interface. :stuck_out_tongue_closed_eyes:
Can’t this function be implemented? :wink:

The best place for feature requests is our issue tracker.

:yum:Yes, first of all, I need to confirm that this feature is not available, and then I will request this new feature.

I just requested this new feature.

Have you tried libpanel? GNOME / libpanel · GitLab

I haven’t tried it before, and gimp2.99 uses gtk3,not gtk4.

Do you have any other suggestions for this feature?
