Is your feature request related to a problem? Please describe.
Yes, the problem is: sometimes we need balanced channels to do some stuff while testing and developing locally, but balancing them manually takes precious time.

Describe the solution you'd like
A button that we can click and have the channels balanced automatically (in the background by polar).

Suggestion

Here is a pseudo-code to balance the channels:

button.onClick((event) => {
  for (channel of getChannels()) {
    amountPeer1 = channel.getAmountPeer1()
    amountPeer2 = channel.getAmountPeer2()
    if (amountPeer1 == amountPeer2)
      continue;
    if (amountPeer 1 > amountPeer2) {
      invoice = channel.generateInvoiceForPeer2({ amount: (amountPeer1-amountPeer)/2 })
      channel.payInvoiceToPeer2(invoice)
    } else {
      // same thing as above
    }
  }
})

I can try do this, but some guidance is welcomed
