The modification is an overlay, displayed on top of all the tabs of the hangar. This means that if you expand the tank filter, it will overlap it, but it will not interfere with making a choice. Just for information.
It works for all tanks without exception. If the tank has no marking mechanics, just put '-'.
If the tank does not have information on the mark, '-' will be displayed instead of numbers. It is ok. Just play the fight.
The percentage does not reflect the top you entered, but the percentage of players you beat. Simply put, it's just an inversion of the top of the statistics.
The window is located on the right side of the sidebar and directly above the list of equipment. Due to the scaling of the interface, the window may slightly climb onto the carriage.
The window includes the current average damage for 100 battles, it works similarly to the total damage from the Lefty modification in the World of Tanks.
The window includes dynamic text that changes depending on what percentage is needed for the next mark. It works similarly to the required damage from the Lefty modification in the Tank World.
With the mod for a double tank carousel, the window will overlap the first tank on the list in the top row.
Added an info panel under the "Fight!" button
The panel contains 3 types of information: The number of battles on the selected tank, the percentage of wins, and the Average damage.
The color of the winning percentage changes dynamically depending on the value, similar to the one in the profile.
