Allow preview ('z') to work in filmstrip
earlier I found that I wanted to look up a detail from another picture, so I instinctively hovered over the picture in the filmstrip and pressed 'z'.
Well, nothing happened.
It could well be a useful feature to allow 'z' to work in the filmstrip, as many other keybindings and functions from the lighttable work there, anyway.
Could the filmstrip be treated like a linear lighttable, including all lighttable related features that don't depend on sidebars?
