Sound recording mode & microphones (questions? advice? best practice?)

I'm wondering if those of you w/experience in sound recording mode might post Pianoteq knowledge you've gotten from that. I'm working w/5 Focals (CMS40) and a subwoofer. I'm very interested in suggestions & experience re:

1. where to where to place virtual microphones  around the piano (are there, in general well-known, guidelines?)
2. where to place speakers in a room? .. height?, distance?, angle?, etc.
3. other considerations?

I know a lot of this is just trial and error (and eventual success!), so maybe another way to rephrase the question is "lessons learned about trial, error, & success ..."

For the (!*_magnificent_*!) developers (thanks very much for the amazing amount of options in Pianoteq!), I'm wondering if more control over each microphone is upcoming. For example:

1. a grid w/degrees of scale (magnified and more detailed view for mike placement)
2. a dialog box to enter x, y, z microphone coordinates
3. tone (and other controls) for each microphone
4. option to completely remove the lid
5. other possibilities? ..
