Clicking on or before the beginning of any of the wrapped line sections of a word-wrapped line will place the cursor on the last character of the previous line section. Depending on the window size this could cause unwanted horizontal scrolling. This behavior happens in ST2 (Build 2219) and ST3 (Build 3010). I think it makes more sense if instead the cursor was placed at the beginning of the wrapped line section that was clicked on.
BTW, which is the better place to post my feature request, here or on UserEcho? This time I posted in both places but I wondered if there was a preference.
