I feel like what we really need is a better way to get community identifiers from the system for a more "conversational" way to designate a posting target in the YAML. I guess it wouldn't be hard to do by building a little more framework around the beempy call where the writer has created a standalone text file of community names, separated from the hive accounts in the system does a simple search and replace before passing it on.
Overall, a good solution to an annoying problem. Typora is a really good editor.
I will work on community integration into beem/beempy and improve this.
