The most difficult task I encounter when wiring switches or outlets is getting multiple devices within a multi-gang box to align properly so I can put the cover plate on.
What are some tips to get them lined up so all the cover plate screws will go in?
Note: I'm not talking about wiring the switches or outlets themselves, just getting the devices lined up within the box since the device mounting screw goes through a hole in the box, but a slot in the device. This makes it easy for the devices to not be perfectly vertical or for 2 devices to be too far apart or too close together to match up with the holes in the cover plate.
I know this is rather broad and there will likely not be a "best" answer. If there's support, I'll happily make this community wiki and would recommend the answers be made such, as well. Except that I don't see the "make wiki" check box that I thought I'd seen before.

Vertical alignment is rarely an issue if you've installed your box level. There's not much play in the mounting holes of the devices. You can usually work a row of switches into a plate without a problem, for example.
To get them horizontally aligned:
Optionally leave the mounting screws just loose enough that you can slip the devices sideways as needed to fit the plate.
