Hi,
if I'm not totally mistaken, the new command-parser of -tree was
supposed to support command-chaining, I remember explicitly talking
about that to sECuRE. So with command-chaining you could do something
like the “bind Mod1+34 exec 'i3-msg "h"; i3-msg "mode default"'“-stuff
with i3-internals.
Iirc the mode-stuff was one of the reasons I suggested command-chaining
as a vital part of any new command-syntax in the first place.
So though sECuRE noted it as „nice to have“ my answer would have
actually been „planned for -tree“ ;)
Greetings,
