This has to be the most annoying aspect of Lightroom since version 1.0. Really, this simply drives me nuts!
Path to my image files:
In library mode with the left window pane expanded to the right as far as possible, my folder names are substantially truncated with tons of space to the left wasted on folder display indenting. e.g. for this year, folder
"20130101 Exploritori... 296" is displayed. I have to hover over it for 3 seconds before I can read the full description.
This is obviously fixed in the "Import..." module with the right mouse click on folder selection to "Dock Folder". Perfect. Do exactly this inside the Library Folders display.
