Customizing the BBPress Formatting bar

Hello,
URL: http://yourtechadvisors.com/forums/topic/test-topic/
I have a few things that I would like to do to the BBPress text formatting toolbar.
1. Remove the del button.
2. Remove the img button.
3. Remove the ol button.
4. Add Emoji button.
5. If possible, direct me how to add hover text over the buttons that says what it is. For example, if you hover over the b button, the hover text should say Bold.
Support access is open.

Thanks.
