[Solved] Better Quote Styling  

Thank you for your suggestion @massimod, I'll ask the team to discuss and add the feature in the future updates.

This is too easy if you want to get it asap. Please try the following CSS code:

#wpforo-wrap .wpforo-post blockquote, #wpforo-wrap .wpforo-revision-body blockquote {
    background-color: #fff;
    border: none;
    border-left: 4px solid #ff8318;
}
#wpforo-wrap .wpforo-post .wpforo-post-quote-author {
    background-color: whitesmoke;
    width: 100% !important;
}
#wpforo-wrap .wpforo-post blockquote{
    padding:0;
}
#wpforo-wrap .wpforo-post blockquote p{
    padding-left : 10px !important;
    padding-top: 5px !important;
}
#wpforo-wrap .wpforo-post-quote-author strong{
    padding-left : 10px !important;
}

All you need is changing the values in the code. 

Thank you Sofy very much.

With a little padding at the bottom and some backgroud color tuning, works and shows great.

Please consider this for your upcoming updates at some point.

Also please consider something like that or similar for Code in a post. Most forums do it that way, it is much more clear and appealing visually.
