I don't do reddit, but I have a few thoughts on the new interface.
1. make the left side tabs the same width.
2. if possible, I would like the product selection (research tab) to show how long each item would take to research with current research numbers.
3. I would also like some indications of what needs to be researched before that can be researched (have to research rawhide/leather before copper ore, and copper ingots before tin ore, bronze ingots before coal/iron ores...)
4. in the buy researchers/vendors I would like to see research time, and money required for the auto build item. money per second/minute would also be good
5. the active boosts panel would make sense to click to use boosts there again (like on the R there to access options for research boosts)
6. An option to auto reset up to level 6 when the reward slider appears.
