Hello Rick,

The goal is to make drawing timing diagrams as easy as possible, and
I do agree about sticking to standard GUI practices, and that should
be
done for each OS.

The program is in beta testing and I know it's not perfect but don't
forget to look at the big picture. Not only can you draw timing
diagrams,
you can do timing analysis and show margins and find faults in
designs,
you can write scripts that automatically draw the diagrams so complex
diagrams can be made with one command, or test vectors or testbenches
can
be generated with one command. If you need to document simulation
results,
it can read VCD formated files, then you can make annotated timing
diagrams from
simulations and include them in design documentation. With actual
logic
functions you can simulate gates, registers, counters, shift
registers, and
other logic functions which can help when deciding if the logic if
fast
enough or the clocks are to fast.

So, keeping all that in mind, if beta users make valid and
constructive suggestions
for improvements and new features, they will incorporated into the
program. Most all
of them will be added before the final release 1.0.
