This is a sister thread to my other thread (https://www.mu-43.com/f43/how-does-multi-point-focusing-work-does-increase-dof-17276/#post160045). I was taking a picture of a group of people sitting around a long round table at a dinner. The person at the far end was sitting probably a good 15 feet from the person sitting at the near end. I used my GH1's view finder to make sure to bring everyone's face into focus, but it was very challenging. So, in situations like this, I think an on-screen "DOF meter" would be very helpful. An electronic version of the DOF-scale that you found on all manual lenses. Algorithm-wise, this shouldn't be too difficult, right? With DOF info on the screen, you will have a pretty good idea of which aperture to use. Do higher-end DSLRs have this feature? Alternatively, an "auto-DOF" feature that someone mentioned can be found in Canons would be very useful too. With newer Pannys that have touch-screen LCDs, you select the points that you want to bring into focus, and the camera calculates the maximum aperture that will do that. I'd love to see either of these features in the next generation Panny.
