It's ultimately for Richard to say but looks like in future releases of Catalyst, a user will be able to update content in real time to the Catalyst without the "Scanning" logo popping up on the screen.

I have also requested the ability to utilize a remote web interface tool to load content so that we don't have to turn on file sharing. Macs as great as they are still run indexing as a background task when you turn on file sharing and this slows down Catalyst when playing back.

Hopefully with a tool to load content, any user could upload a file in real time and have it scanned and ready to play in a few minutes. Of course speculation says that it would still be a bad idea to be running many layers or effects while doing this process.

So bottom line is it's not a feature currently but hopefully will be soon.
