I love this extension so much, @armandocat, that I'm including a permanent link to it in the signature of my posts.
The histogram feature is probably my favorite of them all, but I love the upgrade to it. Easily being able to search a user's post history is exactly the kind of upgrade I hoped would happen for that feature.
I love the floating bar. It's genius. I just wanted to say that. And the side-preview in the markdown editor is awesome. I use Atom to compose my posts, and I make use of the Markdown Preview package all of the time so I can get that side-preview while drafting. It's so helpful. Thank you for adding this.
I love the new features, and I can't wait to give them a try (especially the photo gallery and the GIPHY functions).
Thank you, thank you, thank you.
Update: I do have a feature request - would it be possible in a future update to extend the histogram feature to the replies, comments, and votes? That would be amazing.
