I downloaded it about a year ago and I find I am using it more and more to test my circuits before I build my hardware. I am about to draw up a 4 stage, binary ripple counter with master-slave J-K flip-flops using the app. I'll then move to EasyEda (https://easyeda.com), draw the schematic and use ...

I have a complicated project and I would like to group the circuits by type in the project pane
so that they are neatly organized. The Calc16 example groups its circuits, but I cannot work out how to do it. How is it done?

Looks good

Hi Eugene,

Thanks. I applied the change and the circuit now works.

I built a simple selection circuit with AND, NOT and OR gates in Logic Circuit
and everything worked fine. I then replaced the circuitry with just AND and NOR gates
and LogicalCircuit won't run the circuit. The buttons don't work and the LED does not change
to a darkened colour as it normally does ...
