A few questions about the XNA extension

Hi,
first of all thank You, I follow you since klik & play came out, your software is amazing and the release of the xna extension is a wonderful news.
I've developped few games for xna already and I have some questions about the exporting of the project that may need of some adjustment.
first of all i tried to export a simple platform game i developped with many active object with several animations, i've noticed that each frame is a single images, is a good thing?
in a older project all coded in c#, i was forced to use animation strips for two reason the first is the ram of the 360 that is really low, the second one were the loading time that if there are a lot of images stretches to a really long and painful waiting times, your extension how does manage the loading of all this images?
in that case could be possible to have an update where the active object are exported in animation strip and interpreted by the xna extension?
second in the process of switching frame levels there is the chance to put a loading screen?
if yes how?

the tool it's really powerful but I think this is a huge limit for whom want to exploit to the max the tool itself, please give us a time of an update.
I bought this extension and as i expected it's amazing but this limits all the developpers and so the absence of a wmv player it's quite odd.
I renew my compliments for this great tool, I love it and I'm happy to have bought it.
