Customize GUI

Hi, it’s just a cuestion, can i customize the GUI?
Change some images, some forms, something like that

You can do anything you want if you keep within the license you implicitly accepted, within the GUI you can edit within “advanced settings” the section called

Styling and Logos

Basically if you remove any trademarks or copyrights you have gone too far but editing any *.css files is reasonably within your scope.
