Set focus on first field in field editor

Bumping this. I’m a new Skuid user and digging into tried and true methods. I’m so happy that I found this thread. I was able to implement the first js snippet, provided by Zach above, on a Search component by giving it the nx-field class.

Before I experiment more with this snippet, I wonder, since this thread is 5 years old, are there new/better techniques for controlling focus? Could anyone point me to other resources on this topic?
