I'm mainly looking to:

A) Add a timestamp to the chat for received messages.

b) Change the color/font of the received messages to make them more easily distinguishable from the sent messages.

Is there any relatively simple way to accomplish these? I don't see any styles associated by transmit/receive-side.

You're awesome, thanks for the info.

Ah, that makes sense.

Ouch, that's what I thought. I have it enumerated in my development environment, and that worked, but it's definitely ugly.

Is that going to cause any kind of slowness? We have a possibility of any extension between 3000 and 4999 and I'd rather not add each one manually because that can lead to mistakes and omissions.

As an aside, how would I make it so that user 1000 can only listen/whisper to their queue, but can still see all users?

Is there a way to make it so that a group can see all extension buttons, but just one or two queues? I want all users to be able to see all other users, just not all queues/conferences.

eg:
groupA:SIP/all
groupB:queue/100

user=1000:1234:groupA,groupB

How would I set up this "notifybroadcast" action so that, say, an admin (myself) could use it?

All manual (vanilla Asterisk)

I saw that I can do the groups/buttons thing, but I didn't see the exact syntax.

Can this be used to make the conferences visible only to certain users?

I went by the examples listed and entered "#{CLIDNUM}" (sans quotes)

Can we make conferences/queues only visible to some, specific users?

What is the permission name for transfer to mobile? I have "transfer" set up for my users, but they don't get the transfer to mobile button unless the user has "all" for permissions.
