Match Kit Designer
The Match Kit Designer is a Supporter feature that allows users to design match kits for their team. Each team may have one home kit and one away kit, which may have completely different designs.
The feature can be accessed through a link (or dropdown option) named Change match kit on the overview page of the club.
The Kit Designer has been created by HT-Oxidus, who was Oxidus back then, as a gimmick he put on a website on his own. The extreme popularity lead eventually to the feature being added to Hattrick itself.
