Lads! It's finally here! Peek can now be activated via SpaceBar alone! (3rd highlight) If you've installed the update and haven't restarted your computer yet, simply turn the extension on and off, it'll work as expected. It's so much better having the option natively because if you used the janky hacks to make it activate on spacebar, it would've triggered Peek when you tried to rename a file and tried to add a space in the name.
