I believe staff such as @MajorMcDonalds are already aware of the exploit?
(if not I can share privately, not to spread this knowledge and ruin everyone’s experience)
i have yet to see people going around with large decals.
matter of fact, i do believe 1 player among 1000 even applies decals in the first place. and 1 in 10 000 that goes that far for decals that cover the whole tank.
and the " glitch " it’s rather useful to make custom ones as you can get more details with the bigger ones.
so no. there’s no need.
but the option for filter through settings dedicated to decals as you keep asking for, should be more than enough.
