Hello!
If you open the Add-on Settings Window, it is set to a defined width. There are add-ons that has more settings that others and maybe it would be good to make the window resizable.
In that screen capture, I am using the Slider add-on. Do you see the fields are being squeezed? I think if that window is resizable, all the settings field doesn't look so busy and squeezed.
Or maybe it should be applicable to all of the settings window.
Thanks,
Jackson
