SCP:SL LabAPI plugin that improves upon base-game sinkhole hazards.
It allows users to modify the effect radius of sinkholes, and adds a teleport radius to the middle that sends players to the pocket dimension when in range.

Yes, this is BetterBetterSinkholes 
This version is better because it doesn't require Harmony, and it isn't majorly bloated.
This plugin is literally less than 60 lines of code, and it's all in one file.
Little mess, little fuss, easy-peasy.
