I have been looking for a punishment gui plugin
but cant find one that works for the life of me any idea where I could get one that is easly customizable (version 1.11)
I have tried over 10 plugins and can not find one that would work with tempbans/tempmutes.
I know how you feel bud, specific plugin features are losing support with newer versions coming out. Either because it's more difficult to code for or the developers of the plugin lost interest.
I tried researching a bit for you. The only specific plugin I could find that supports 1.11. Not sure if this works or how much you can change it's GUI for your needs. Hope I helped.
