Since there is rain, thunder and weather now, there should really be an /pweather just as /ptime day ( /pweather sun ) ( /pweather thunder ) ..... That's my suggestion.
If this is a suggestion to toggle rain and snow and all those on/off SUPPORTED! I am sick and tired of not being able to run in Antiqua if its raining :/
Also, this shouldn't be a Ext Commands thing. People shouldn't have to pay to turn off lag... Though you could download spout and turn particles off.
If possible, it would be nice if all users could turn off weather once it starts - simply for them alone. However, if a donator could have the ability to turn on and only see weather, without the effects, that could be nice. I'd love if I could always have it look like it's snowing in my town - even if I have no actual snow falling on the ground.
