Hi all, just taken delivery of my new GX8. A very nice camera it is, but I do have a couple of questions please. When in playback mode, is there a way to program a button to do one touch magnification (rather than having to use the scroll wheel). I've found that 8x appears to be around 100% view ? Secondly, if we have to use the scroll wheel, any chance of re-mapping it to the front dial rather than the rear one (feels more comfortable for me), and have the rear dial skip through images ? Thanks.
