Obsidian Extension Handler

An Obsidian plugin to allow editing (and creation) of files with custom extensions.

⚠️ Adding ext/ft pairs: For setting-changes to take effect you have to restart Obsidian, this will be changed in the future.

ℹ️ Note: Plugin has not yet been added to the Obsidian community plugin list, and will have to be installed manually.
