Very thanks for this. I have tried your feature branch but it seems to
be working only on gui interface. I tried with -nw in xterm and they are
not working. And disabling the toolbar in gui they didn't work either.
Is this supposed to work like this?
I pushed now to the branch a new mode that supports switching tabs
without using the tab-bar in xterm:
'list-tabs' displays a list of named window configurations for switching;
'make-tab' creates a new window configuration;
'delete-tab' deletes the current window configuration;
'switch-to-tab' switches to the window configuration by its name;
'previous-tab' switches to the previous window configuration;
'next-tab' switches to the next window configuration.
All created tabs are still saved in the desktop file.
