Events+ Making Multiple changes and adding functions? Possible?

Hi, I have a couple questions if it is possible to add/change these things with the Events+ plugin.

1. Can you have each category (the events within that category) assigned to a different color? So Category 1 events will show up on the calendar blue, category 2 events will show up red... etc?

2. How do you ONLY have "I'm attending" appear on the event listing page AND is there a way to change it to just "Attend"?

3. How do you set a specific time when the event opens for sign-up and a specific time when it closes?

4. When the event is full (at capacity of signups allowed) can you create a waitlist for additional people who click "attending" and move them to the original event if those who were attending decide to retract their decision?

THANK YOU! ANY HELP IS MUCH APPRECIATED!
