Hover can be very frustrating when selecting text etc. Longer delay (eg 1500ms) solves this but when you actually need the hover information it is frustrating to wait.

Having the full hover information by pressing control and hover the mouse on specific code is very nice. Please leave this functionality while let us disable the simple hover (the one without pressing Ctrl). In other words separate "hover" and "ctrl+hover" functionalities, with two seaparate options for turning them on/off.
