Can someone explain what "Limit Others" does? Does this allow me to grant higher TC limits based on players? I'd like the ability to grant some players the right to have more than the regular TC limit.

Hello,
You have 2 standard Limits : "default", applied to all, and "vip" applied only to those with cupboardlimiter.vip permission.

The dynamic limits works as follows:

If you have the variable like this (it's an array of integers) :
"Limit Others": [
  6,
  12,
  2
]

3 new permissions will be added :
cupboardlimiter.limit_1 => Allow 6 TC
cupboardlimiter.limit_2 => Allow 12 TC
cupboardlimiter.limit_3 => Allow 2 TC

You can just grant the permission(s) you want to players.

Remember that if more than one permission is granted, only the biggest count of TC's is taken into account.
