So maybe I'll concentrate on sensible grouping then and forget about hiding. I'm thinking about creating an "Internals" group in each actor with subgroups for JCMs etc., anything users should not normally dial in directly.

As for master sync, I guess I'll have to do some experiments to understand how it works with complicated dependencies and then decide on a case-by-case basis. To be honest, so far it looks like a complete nuisance to me.
