Two weeks ago, I made a Reddit post about this mod I created. I think that it's mature enough, so I'm posting it here now.
Here you can find the Github repository where it is hosted at. You can find most of the answers to your questions in the README, or in the updates on the Reddit post.
If you have any questions, please go ahead.
PS: well it seems I can't post links now, so I will edit this post later. To find the mod, go to Reddit (r/CookieClicker) and search for mod_cookie_garden_helper
