I like it and had been using it for a bit. Definitely appreciated the busy upvote and the slider before I had enough SP to have one here on Steemit. But the reason I had to stop using it to create new posts is the image hosting.
An important part of my process when I create a new post it to share it to various Discord channels for post promotion/upvotes, and the images won't show with the steemit link if you post with busy. I suppose I would have to post the busy link instead of the Steemit one, but I'm otherwise tracking everything for my steemit links.
If someone is going to be 100% Busy or doesn't care about posting links to their steemit URLs on discord, this is not a consideration. The pictures show fine when posted with Busy but linked to the Steemit URL when on someplace like Facebook, just not on Discord.
