My CircuitLab bag of tricks
 
I am an "inventor at heart"; so after I started working with the CircuitLab  simulator, I immediately began to come up with various clever tricks, which are much easier with the simulator than in reality.  Here are some of them: Step-by-step "building scenarios".  I make them very easily, "back to front". I start with the last, most complex schematic, and gradually remove the elements from it; thus I arrive at the first, simplest schematic. I surround schematics with a gray border having the same size. Thus the same dimensions (scale) of devices are obtained and they are drawn at the same place (important for step-by-step scenarios). This representation is specific to me and serves like a "watermark". As an example, here is the first schematic in a gray frame extracted from my answer  to the SE EE question  Output voltage level of TTL gate . simulate this circuit  – Schematic created using  CircuitLab Decomposing simulations into multiple frames....
