One thing Panda is better and worse at at the same time compared to Bear is that the first line of the document does not affect the name of the document. Although it is cumbersome on one hand, on the other it makes us able to have some datas on top of the title such as chapter number of a book or a tag or a geolocation, those I want it to be the first I see on the document but not necessarily the title I want to make.
I think it would be a great to see the first heading become the title of that document, or at least a toggle for it.
Cheers!
