Hmm... I actually like the bullet styling better. I don't think there is much if any custom content that uses the center formatting. I'm okay with some minor changes, as long as it doesn't break anything in a noticeable way.

By center I mean the formatting as shown in the video.

@ragesoss I have made the suggested changes. Please review. Thanks!

That's what I thought you meant. I think this is fine. I think you can remove the aligncenter center option by editing the tinyMCE config in text_area_input.jsx.

@ragesoss I have made the changes.

Please update the screenshots to illustrate all changes (including the change to the text editor), and then this should be ready to go.
