When not too constrained by size and particularly for prototyping, I tend to use short descriptive names that are not too hard to decode. For example you could use Cby* for bypass capacitors, or maybe if you have a series of LEDs, then you could have Dr, Dg, Db* depending on their color, and similarly Rr, Rg, Rb* for their respective resistors, or Rpi* for I2C pull-up resistors, etc. Sure you could have a look a the traces to find those out, but it's not always straightforward. This makes a big difference when debugging boards IMO. For example now if you see that your blue LED is too bright again (as is usually the case ;)), you can just look for Rb* and fix it without the schematic.
