Searchable dynamic criteria field name

[makseq]

First of all, thank you for this awesome project!

Is it possible to make dynamic criteria field name searchable? I have more than 1k entities there and it's difficult to navigate.

@makseq Thanks for your comment. This seems to be like very useful extension. It would only need to find some select widget and use it.
I don't have time to make this, but if you or somebody else make PR, I will surely review and merge it.
