It would be a big productivity booster if you could hover over a method call and not only see its definition as used, but if desired expand a list of its overloads. At present you have to switch to the browser and look it up in the docs.
For now I think this could be implemented as a right mouse click on the keyword and add "View Overloads" to the other options already there. It would be greyed out if there is only one overload.
Down the road I suppose a pop-up hovering "window-let" might replace the tool tip and you could hang this and other future features (e.g., suggested corrections and completions) off of that.
