Nice to meet you, VuBce. I admit that I perhaps only skimmed over this thread, as I'm getting tired of reading the same things over again... But many people are confusing Rock for just the config panel, and think that it's just a change in features.
Anyway, it's been out for 3.5 days. And, while it may not seem like it sometimes, ckk (like all authors here) has a life besides drilling out code.
I was only trying to point out that there was no big scream of the community here to change the way of configuration.
Does there need to be? There was no big scream of the community for a new framework, either. Well... Yeah, Ace2 has issues. But still. It's ckk's addon to do with as he sees fit. He takes all user feedback, provided it's given in the proper channels (ie, jira), and does with that as he sees fit. People just need to be patient, use jira, and either revert or wait (patiently).
I understand that everyone has their preferences. ckk knows that some people want their drop-down menus back. It's been posted on jira (which is the place to put bug reports and requests, btw). Just be patient.
Anyway, right-click on the FuBar where you want the hidden icon to show. RockConfig automagically opens to the options for that specific FuBar. On the right side is a pull-down menu. Check/uncheck the modules. It really is as simple as Orion says. It looks different, but it takes the *same* amount of time.
