What I would like most:
1.) The option for buildings to be greyed out when you try to buy x100, but you only have money for less than x100.
2.) An option to switch to other notations (10^x, long scale, e^x)
3.) A way to buy all cash upgrades / all cash managers you have money for with one click, those 50(?) clicks on each reset aren’t really needed.
4.) A total cash per second somewhere if you have all the cash per second managers.
