Arrow and upgrade

Please… do something about those arrows that appear throughout the game… I don’t necessarily want to upgrade a building all the time…
And it breaks the immersion of this game… which is very beautiful.

My wish :

*Default (Game Mode): No arrows are displayed, preserving immersion.
*Tool Activation (Upgrade or Build Mode): When the player selects the build menu

You can toggle those widgets with F2

F2 will remove all icons above buildings.
