[otrs] ACL feature on OTRS are very poor. We need improvements!

As I've discussed on http://bugs.otrs.org/show_bug.cgi?id=5498, I and I think several other people need some improvements on ACL feature. It seems that bugs/improvements reported on bug tracker about ACLs take very long time to be fixed/implemented and, in my opinion, ACLs give the flexibility needed in a more complex production environment. Flexibility not reached only with options available on Sysconfig. Please, read my comments on bug tracker and give a feedback! I really need those functionalities until OTRS 3.0 release.
