Just a quick note for now: yes, once the TL'09 release is out,
scripting is one of the first new features I want to include in the
development trunk.
Don't assume, though, that the [first] scripting language will
necessarily be Lua. Although Lua certainly seems to be on the rise in
the TeX world, another very widely-known language is JavaScript, and
it happens that Qt includes a lot of support for this right in the
application frameworks. By using this, we can get a huge amount of
functionality "for free", without the need to write (and maintain)
extra code to interface the scripting language to the application's
built-in objects and functions. So I think it makes sense to try this
first, and then consider whether any additional language(s) may be
needed.
I have an experimental version with JavaScript support (based on
Stefan's Lua patch, but much simpler because it doesn't have to
provide the Lua interpreter or the "glue" code) that I will make
available after we branch the stable TL release (shortly).
And yes, the ability to have sub-menus (and shortcuts) for scripts,
and easily modify them, is certainly desirable.
