No, it should not -- e.g. pressing "l" for "set log y" in X11 would change
this property globally, thus also for the other terminal, which is probably
not desired.

This should not depend on whether window is persistent or not.

Question is whether "unset mouse" operates on the current or on all
mouseable terminals. Currently only on the selected one. We can keep this
feature, and then it is not bug.

Works nice, just a small annoyance: you have to move your mouse so that the
window resizes itself to adopt space for the mouse bar. Could the resize be
called automatically when mouse gets on/off?

It should inherit the ruler at its x,y position so that the ruler propagates
at the same x,y for all subsequent plots.
Could you please patch it?
