Hello guys, I changed some things in my mod I shared few days ago. This time I did entire technology/Reform tree overhaul. Things I done: 
You can see all the changes in "images" section. Their title will be "Update 1.1" !

- You need to wait 4 turns instead of 5 to get a reform

- Taxes are doubled (you get double the money but at double cost of public order and food) this change is made due to reform overhaul because you get a lot more public order now.

- Every aspect has different bonuses completely. Detailed:
