but..

It would be even better if the menus, and remote functionality would follow whatever is the frontmost app. Is the ability to do this already there, and I'm missing it?

I'm constantly hitting the remote thinking i'm controlling the front app, but remote buddy is somewhere else, and it often takes quite a bit of menu action to get where I need to be. 

thanks for posting.

It's the default behaviour of Remote Buddy to always automatically 
select the right behaviour for the frontmost app. Or, if it doesn't 
have one for the active (usually the frontmost) app, select the right 
one for the applications running in the background (i.e. player apps).

So, unless you explicitely activate a specific behaviour, Remote 
Buddy should just work as you describe. If you do explicitely 
activate a behaviour, this one will stick though, no matter what app 
becomes active. To deactivate this and return to the auto-mode, just 
press the menu button and use "Deactivate behaviour". The menu 
disappears. If you press the menu button the next time you should see 
that it has chosen the respectively best fitting behaviour.

If this shouldn't help, please let me know with which applications 
you are having problems, what actions you are performing in Remote 
Buddy's menu and how Remote Buddy's automatic choice differs from 
what you'd expect.

Best regards,
