Obsidian support

We invite all users to give us ideas on how **you** would like Cleft to work with [Obsidian](https://obsidian.md/), from sending notes to whatever ideas you can share with us. Kudos for initial suggestion to integrate Jim, Sean, Fabian, Michael and Christophe. We would love as many of your insights into how we might implement this to make a Cleft a better place for Obsidian users.
