Thanks Mark - I think as an excercise adding an alarm capability to the
clock seems like a nice thing to do. Looking in to how do you dispatch
messages from LCB to LivecodeScript? I see two option "send" and "post"
wandering what the difference is...
I also have a general question about the scope and robustness at this stage
of compound widgets. As an example if I am looking to dynamically move
clickable sprites around can I do things like add a number svg icon widgets
and animate them?
It would be good to have an idea about the speed of using widgets to do
complex layouts and interactions like this - as compared with doing the
same using groups and Livecode script - in what areas would I expect to see
a speedup, and what areas would be about the same or slower for now?
