[AuriRex]

Work In Progress
adding the option to use custom notes for other players as stated in issue #21

(modified SiraUtil required, pull request created)
changes have been merged, v2.4.0

feature todo list:

• Custom Notes for other players
• Setting to change the behavior (dropdown list)
• Currently selected notes for everyone
• Choose new random notes for other players every match
• Choose random notes for other players using their id as random seed (same notes every match*)
• A way to change this behavior in a multiplayer lobby
• Use MultiplayerExtensions to send the hash of the currently selected Custom Note to other players
• Download not installed Custom Notes from ModelSaber (+ settings toggle / only download verified models) excluded for now, will work on that at a later point maybe
• Choose the same notes as party match host?

*with the same set of Custom Notes installed

bugs / issues / things to improve:

• connected players notes are rotated wrongly.

things that require an explanation:

• A custom event handler for NoteCut and NoteMissed Events because these events don't appear to be called on Multiplayer notes: CustomMultiplayerNoteEventManager.cs
