My experience with Panda has been excellent so far. The only missing thing is file transclusion, i.e., the ability to tell Markdown to insert the contents of another file inside the current file being processed. For example:
This is some text.
{{some_other_file.txt}}
Please, do not forget to add that in Bear 2.0. I believe that should be an easy task, right?
