I am follwing up on corunography post (Dec 27 2009).
To answer your question: yes, I am also frustratred with deck switching / live composition, well by everything that is related choosing the right clip to play.
I think I would like to use R3 exactly the same way as you (that seems to be a pretty low requirement for the best VJ software in the world): QUICKLY look for the clip I want to play NOW!
That is what is still preventing me from using R3 for real (I stick to R2). This is too bad, I already reported this issue, and was hoping that R3.1.3 would eventually fix it.
Another thing I noticed: let say I have a composition with 30 decks. I save the composition and quit. When I re-open R3, it loads my last composition (OK) but everytime with a random subset of decks.
And double-clicking on a a deck name takes ages for loading it.
Sometimes I revert to daxx's solution, but that is really a pitty.
I really like Resolume and the team is nice when answering questions.
I am sure they do their best, but I don't understand why they don't focus more on this kind of issues.
