Request for SINOVOIP: Create general categories for all boards in forum

Hello, I think that will be a good idea creating general Android, raspian…and so on OS general categories in the forum, and creating new general categories such programing (Java, C, Phyton…), rom cooking category etc, because a lot of things and lot of methods are common used in all boards. Having a specific category for each board is good but add some general categories will be better
