Gear S3 Hidden features

I was hoping to find some new features. Almost all of these are crossovers from the s2. Good for those that didn't know I guess.
 
thanks.. didn't have an S2 so didn't know about some of these (screen shot, camera app) .. good to know
 
for non s2 users, I learned you can re-order your apps right from the watch .. similar to how to re-order the widgets from the watch. In the apps menu, click and hold an app, you can then drop it where you want, including the next / previous page. you can also delete apps right from the watch. (thought this all could only be done from the gear app).
