Some questions about the upcoming VST support

1. (Assuming it's supporting 64-bit plugins right off the bat) will there be native bridging for 32-bit plugins?
   I'm sick of DAWs skipping out on this (or getting rid of such support, in Ableton's case) as there's a large number of (albeit older) plugins which only exist as 32-bit, and a few of the ones I have don't function properly through Jbridge.

2. Will MuseScore scan for plugins while it's running (when user tells it to) or before loading?
   I would prefer not to have another Sibelius scenario where I have to completely nuke and reinstall because it crashes due to "one of a thousand" plugins bringing the whole thing down, and being unable to change the settings because the scan happens before Sibelius actually loads, and THEN have to guess which random plugin caused the crash... At least Reaper skips the problematic plugin when you launch it again, but that's neither here nor there.

(also if I'm posting this in the wrong place, I'm sorry feel free to move it to where it belongs)
