Loader Cliplist

I opened an older project (something from fu6) in Fu7.7 and Fu8 beta and had a Loader with a cliplist.
but the tab for the cliplist is gone in the BMD versions in the timeline i can see the different clips but i cant edit them anyhow.

so my question is:

How do i gain access to the cliplist feature of the loader in BMD FU7 and later?

I think it's a 'pro' feature that's now limited to the Studio version.

is it?

cant find any information on that

No, it's not in Studio either.

hmm.. can't find it either. Used to be an option in the loader setting of preferences.
