Already some CAD guys have a look for doing a new/improved back cover, I got the resources to produce them if someone has resources to sell them. Also known replacement battery retailers will do a larger battery with an extend cover. there is no need for us to do this, there are professionals out there waiting to be asked.

A widget with user interaction is not a solution for this, there shouldn't user interaction be needed.

If this is not about software I am out. I wont do testing on a new device which is €500+ to loose my warranty... maybe I order the housing some day to do some reverse engineering and try some ideas but that will be it for now.
