Cool tool, my reddit interface became much better!
I have an offer to make it better:
Can you make "hide sub reddit sidebar" separate settings for subreddits?
Answer: yes, i mean adding a blacklist or something to hide it on certain sub reddits.

Nice extension, but please optimize it, as it consumes a lot of RAM and slows down the browser.

A great tweaker for how new reddit looks! Hopefully this extension grows and adds features the same way that RES did for old reddit!
