Currently doing some work which requires me to compare multiple files and register the names of some of the changed ones in an external system, I dearly miss a feature to copy the name/path of a file from within the "Synchronize Directories" window.
I do understand it can clutter the already-complex right-click menu, and I could live with the option to F3 / Shift-F3 and copy the filename from within Lister. However, it does not support one

Doing a Save-As can be possible, although cumbersome, walkaround but it does not provide a solution for when I need the full path of the file...
I think the best solution (and easily implementable) would be to add 2 options to the Edit menu of Lister: "File name to clipboard" and "Full file path to clipboard".
