Thank you, @PaulWatts . and Welcome to the Hook Productivity Forum !
they wrote to a Hook liaison :
We have custom URL, such as:obsidian://open?vault=Obsidian%20Help&file=Start%20here.md
We also have an API now, so you can write a plugin and access the custom URL automatically.
She adds
I checked and yes, if the user right-clicks on a note in Obsidian, they can copy an Obsidian URL.
and pointed us to Plugins mini FAQ - Basement - Obsidian Forum Plugins mini FAQ - FAQ - Obsidian Forum
So, I’m truly delighted and our dev team will move on this ASAP. Thank you all for your interest and extending our brains with your brain power!
