Yeah I use it every day. Mainly for peeking into web pages so I don't have to go backwards or forwards such as reddit or ATRL posts. I also use the keyboard cursor quite often too, and also to quickly go to battery settings.
I tried at first, but when it first came out, a lot of apps didn't have the feature yet so I just forgot about it. It was convenient, but ultimately I just forgot it was there It still doesn't work in the Chrome app
