Dvorak Heatmap

I would like to be able to set the heatmap to Dvorak layout.

I think this falls outside the previous request to have WhatPulse log other language keys such as ‘â’, or at least comprises a much simpler request.

I use Dvorak and my heatmap looks perfectly fine.

The heatmap within the client is QWERTY only.
