There is no explicit explanation in the readme of what the $ sign does in the modified querySelector() function. I do believe I figured it out by testing and by looking at the _selectTree-function and added a line about that.
I expanded the example on selecting one or many elements with some text I believe makes it more readable.
I fixed what I believe is a typo in the old line 185 where a misplaced colon was confusing me when reading the docs.
I suggest three changes to the readme file:
