"This command does something very different than what you want."
Indeed, it pops up an error message when I wanted to copy the path to the clipboard.
I observe that the "Copy file path to clipboard" entry is present in the right click menu when I am moused over the edit window. It makes sense for this option to be present when moused over the edit window. At that point I want the path to the file I'm editing. It's an option I've often wished for.
I observe that "copy path to clipboard" is a working right click option when I mouse over the file list in the "open" pane. But this option is lacking when I mouse over the "files" pane (which lists the files now open).
In earlier versions of Slick, I would do a "save as" and then copy the path displayed. The right click option to copy the path is very useful in any pane displaying a file.
