Display filename over | beneath thumbnails in lighttable and darkroom
When shooting a lot of images, some series that have images that look very much alike, it is much easier to scan the thumbs page for the right filename instead of going over all the thumbs with the mouse and keeping a constant eye on the left panel with file info. Same goes for the filmstrip in darkroom. When I need an image with a certain filenumber, in darkroom I could be clicking 15 thumbs to get the right one, or go back to lightroom and search for the right image there. In this case, a could ofcourse first add green labels on the images I want to work on in darkroom, but sometimes that doesn't work and I need to know the filename/number.
Aftershot Pro has something like this, see screenshot.
