Gerald and list,
Sorry for the late reply.
I was thinking about releasing lxterminal without GTK+2 support for a
long time ago, which I added the requested function you'd like.
(redone with GTK+3)
However, I was wondering if that GTK+3-only release could be accepted
between LXDE users. Or, should I stick with GTK+2?
And, I need help on GTK+3 resizing technique.
