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?
