is it possible to create a panel only for admins, based on this plugin? If yes, is it a big effort to convert it into such a version? What would need to be changed in order to get it shown only for admins?
It is possible (because nothing is impossible ). You just have to ask if the player isAnyAdmin() and if that is true, then show, otherwise do nothing. Unfortunately i have freezed the development for XAseco2 plugins a long time ago (because i'm working on UASECO).
Developer of various plugins for XAseco/XAseco2 and MPAseco,
like Records-Eyepiece, TM-Karma, Alternate Scoretable...
