When running "pulseview -V" there should be the same/full output of version info about PV itself and all libs etc., i.e. all that's listed in the About box (i.e., also similar list as in "sigrok-cli -V").
I'd suggest that the About box also includes the very Pulseview application version in the text field (and not in the text field's caption). So that this application version information resides with all the libraries' versions, and is available for clipboard access.
