#28 Switch source with destination button should preserve intuitive paths

[me]

As of version 1.3.0, the existing button switches the paths systematically, but a reasonable approach would be to switch only source and destination paths, excluding the last directory from the source, serving the pull action behavior.
For example,

source:       ~/Downloads/Dir
destination:  ~/Documents

should become, after toggling the switch button, as,

source:       ~/Documents/Dir
destination:  ~/Downloads

Hello,
Thanks for the suggestion.
I think it's an additional feature: I won't replace the current one as it's been like that for almost 20 years and it has its uses.
Cheers!
