Keep up the great work. I have made some suggestions to MangoSteem in my post.

Suggestions

1. Make the process of creating a channel easy.
2. Ability to use the slider while up-voting a chat.
3. Simplify the process of creating a channel. You can actually have a bidding 4. system to create a channel and use that Steem for the development of the project.
4. Make the channel description more visible.
5. Allow editing of chats for at-least first 5 mins. Since it is a comment it can be edited for 7 days.
6. Threaded reply in chats could be great.
7. Ability to sort the chats based on popularity like we can do in comments.
8. Ability to make a comment a sticky post for the creator of the channel. He can use this for promotions etal and if anybody is thankful for the channel they can upvote that particular comment.
9. Work around for the 20 sec comment/chat posting limit.
