A while ago I had a fairly strange problem: I was taking pictures with a manual 200mm lens, and had trouble keeping the subject in the frame. Why? Because, during a burst sequence, the display is turned off. I was focusing manually from LiveView, so couldn't look through the viewfinder.
So, here's a module that implements this tweak: during a burst sequence, it shows a live preview of the captured images. RAW only.
Also included a tweak that limits the number of pictures in a burst sequence (for example, if you want to take 2 pictures on a single shutter press). I'm not sure where this could be useful, but was simple enough to write.
I wrote this about one or two months ago, but didn't get the opportunity to battle-test it yet.
If it works fine on most models and people find it useful, I'll include it in the nightly.
