When you load the Setup menu in Salesforce Lightning Experience, the search box is focused, and then for some reason loses focus quickly.
So you may start to type something only to then realize that the input became unfocussed, and you need to retype it.
This is frustrating, so this extension waits for the input to unfocus, and then refocuses it.
Works like a charm, simple and useful
Bless your heart!
This has driven me insane since the first time I went into the Lightning Setup Menu. Thanks for 1,600 less frustrating moments per week in my life of Salesforce!!!
