Thanks @irelandscape. :D - We learned a lot about Steem (and the very sad state of affairs surrounding API interfaces and Markdown specifically). Again, the ace we had was the bulletproof build and scaffolding process from Quasar. It just worked!!!

Yes and I learned a new thing about electron.
Never build an electron app before. 😀

You should check the issues on the git repo. They found what looks like a type error within dsteem, it seems.
