Hello samo_dadela.
Page peel is one of those features for which it’s hard to please everyone all of the time, though we would like to and try to. 🙂 We tried to make the page-peel as inobtrusive as possible, and as configurable as possible, but at the same time keeping the GUI simple.
What about one of the remaining corners at the bottom?
Making the page-peel less sensitive would upset those who want it to appear immediately, likewise adding more options to set how sensitive it is would clutter the client GUI.
