Battery charge level display

The ability to customize the start screen (model screen or whatever it is called) is an outstanding feature which I really like.

However, I find the battery display widget a little bit disappointing (using Deviation 5.0 / Devo 10). It only displays the current battery voltage - but a percentage value (or a progress bar display) would come quite handy.

Is there any way to add such a percentage widget to display the battery charge level?

Percentage is somewhat pointless.. i.e. fully charged rechargable batteries will have a much lower voltage than new, non-rechargable ones (1.2v vs 1.5v nominal), and would display a lower percentage value. It's also much safer to see the actual voltage and know if your transmitter is going to last a while longer or not.

Even the original Devo 10 firmware was able to correctly display the charge of my Lipo (in percentage bars), so I doubt this would be a problem.

The user could also enter a top and bottom value (highest voltage, low voltage) that Deviation could use to calculate the percentage display then.

This would be easy.
