What characters are good to add to a prototype PCB that makes life easier?

I have almost finished PCB prototype assembly except for adding good quality for easy life. Are there any advice?
  • Adding useful information on the silkscreen to designate functional areas/pins/traces. Revision number.
  • LEDs for power and micro activity.
  • Test points at important places in the circuit.
  • Connecting a spare communication channel to a header.

Why do you order a laser stencil?

I am looking to order a prototype PCB and all the manufactures I’ve gotten a quote from all offer to include a Laser stencil, some charge for the stencil some are given free with the board. After looking online to me it looks like the laser stencil just shows the outlines of the pads. So Why have a laser stencil? what advantages do you get from having one?

Why do some through-hole LEDs have flared leads?

I have worked with many through-hole LEDs over the years. I ordered a bunch for a personal project. I did not notice they have flared leads until I used them. I’ve never encountered these flared leads before. What is their purpose?
