There is an idea, let when holding an icon in the mobile toolkit appeared its description, like in the screenshot from the game (can not be in the center of the screen and below). This would be very useful both for newcomers who do not know what buttons are responsible for what, and for those who put new plugins. Especially considering that not all new plugins have an icon for mobile toolkit
I apologize for the translation. The inscription does not have to be in the center of the screen, it can be lower.
