feature request: default filename with "save as"

[bspinoza]

It often happens that I have to copy my program code on an usb stick from the JB editor.
But when you do that, the default filename is "*.bas". 
It would be convenient to get the old filename as default name.

There is a nice option in Notepad++
Save copy as
it does save file under new name / new folder position
but retains old name / old position.
(but yes, it filled by default with old name)
