BITS PS Station Swap Helper

swap.js

// Usage:
// Paste the following in the console once on each reload.
// After that, type `x(first_index, second_index)` and press ENTER.
// Example: To swap 13th station with 75th station, you'd type:
// x(13,75)
// Example: To put 50th station at 2nd position, you'd type:
// y(50,2)
// Remember to save afterwards. :)
