This is a technical suggestion that would help with lag on certain computers. Light sources and vision calculate the area they affect through ray-tracing. Having a lot of these becomes computationally heavy. My suggestion is that the number of rays the tokens uses should be adjustable per map basis. This would allow gm's to lower the rays on more complicated or larger maps. This change would make the platform much more accessible for people who might have older computers or wish to play through tablets.
