Easiest way to add custom button in editor or how to use default editor for all site?

Hi,

I would like to add a custom button. I am not a programmer so I rely on plugins. The plugins I used (Visual Editor Custom Buttons) works for backend but does nothing to the frontend (question & answer forms). This is when I realized DWQA uses its own editor.

1. Is there a way to set DWQA to use the default editor so that when I make any changes, the change goes in affect to all editors in the site?

2. I noticed some of the methods mentioned in the forum changes the editor only in the answer form but not the question form. How to change it so that any modifications goes to both answer form AND question form (or even better, changes the whole site)?

3.Why does DWQA have to use its own editor? Why not just use the site’s editor where the plugin will be installed in? Won’t this save the trouble for people that have customized their own editors?
