[Solved] Hide Avatars in Recent Comment Widget

Thank you @infober-art-nl,

 1) Is it possible (via CSS) to hide the Avatars in the Recent Comment Widget?

Yes, It is possible, please use the following CSS code, add it in Dashboard > Comments > Settings > Addons > Widgets > "Widget custom CSS" textarea, save it, delete all caches, do CTRL+F5 on frontend.

.popular-comment-author-avatar-box {
    display: none;
}

2) Is it possible to set the length (number of words in shortened excerpts) in characters instead of words? maybe something for the next update?

We'll take it into consideration for future releases.

Is it an idea (or possible) the put the #number of Active Comment Threads (and Most Commented Posts) so like you did on Most Active Commenters 
inside the black circle instead of below?

I'm sorry, but I don't follow you. Could you please explain using some screenshots.
