Unfortunately for me I'm a little green for yours answers. Been coding for a total of 8 weeks and only in 1hr byte sessions.
At this point I'm only using the custom gui module and adding references to drag and dropped elements.
As a beginner I find this manageable and am slowly learning the code as I wrote and rewrite little apps borrowing sections of code from here and the examples.
I can easily make a digital clock. Or customise the analogue clock. What I can't do is make two and count them backwards.
Ideally I'd like to reference ui.labels in the module for clock displays simply because it's at "my level" of understanding.
Thanks again all
