no more dviout
When "Option -> No more dviout" is checked and
dviout foo
is executed from an external program or the command line, the checked dviout (by default, the newest dviout or the last dviout when the limit of dviouts specified by -multi: were started) displays foo.dvi instead of starting a new dviout(the dvi file in the view closes).
This setting is effective for the newest one. If all of the dviouts are exited, the settings are canceled and return to the defaults.
