Drupal 7 – Advanced Forum Quote and Editable Reply (Frustration)

I have three questions:

1.) Why is so hard to simply have a forum using the Advanced Forum module where users have the ability to create a reply, then edit, it after they post it? I’ve scavenged the internet, drupal’s website and this site as well and, to much frustration and exhaustion, I cannot find a solution in ANY module. Any suggestions on this?

2.) Also, am I struggling to simply get a module that gives me the ability for users to quote another user, or at least make the quote icon in the current comment Editor to be seen by users more clearly to users. Is it possible to edit the position of the quote icon on the default editor?

3.) Finally, is it possible to put default text in the Comment editor when users want to reply to a topic?
