In previous software you could change the subheading of your post. In other words you could have your post heading different than the thread heading.
How about my GIF avatar, its not working properly?
There are no subheadings now, as you can see only time and post numbers are appearing at top of every post
And about your GIF Avatar, we are continuously working to fix these minor glitches, Insha Allah it will be back soon too.
