I ~~am sure~~ hope somebody™ already thought of this. Feel free to advertise your project here.
P.S.: Image transcription:
Patrick from SpongeBob SquarePants gesturing to the left with open hands:
Somebody should take document type conversion from Pandoc and version control from Git

Well like uzay said, basically just an office GUI that allows me to import/export into a lot of formats and automates document versioning away.
Do check on eMacs. I know it does a fantastic job for org mode but I’m not fully aware how close markdown support is.
