1) In general yes - starshaped one 'layer' walls.

2) Good. Music will be useful also for the new edition for MTW2 so it is always welcome,
The main thing is to have the music which fits the mood - battle music especially.

3) The new animations from the patch - only here they do not have low res bifs and use high res all the time, slightly better graphic cards automatically re-scale them as required, worse apparently can't.

It works well on slightly better computers ( on 64 grapgic card it works marvellously), but in PMTW 2.0 I will give the option to choose weaker animations too.

The notes are of no consequence - they were used to mark places for new bow shooting animations, those however might not appear...

They do not appear in the game anyway in no way.
