First impressions after few hours

Hello I just bought the game but there are two points that make the experience less enjoyable.
1 ° Being French, my keyboard is not adapted to the keys, and impossible to change them
2 ° When unlocking a technology (improvement), impossible to know precisely where it is on the production line (example, I just unlock the central lock, I have to review several installation to find which allows me to add this feature).
I hope this review will be considered. Thank you
(Sorry if i posted this review at several places)

Hi, it should be that hovering your mouse over the researched item in the tech tree will tell you which slot has had upgrades unlocked by that research item.
