@arcandio posted a nifty hack that allows making use of jump lists under Windows to directly access a particular vault or page from the task bar. Since it is buried in a feature request thread, I’m re-postiong it here.
This is really helpful for Windows users, particularly if you have multiple vaults.
Essentially, you create a shortcut on your desktop or in some special folder that has the Obsidian URL (a URL starting with obsidian:// that can be generated with the “Copy Obsidian URL” command) of the page or just the vault as target. Then you drag that shortcut to the task bar. Now if you right-click on the Obsidian icon on the task bar, you will see all of these shortcuts in the jump list, and you can directly access them without starting Obsidian first.
