[Suggestion] Increase size of "dragging" visual bar to prevent selection of the wrong clip.

in hight resolution monitor is very difficult to see the vertical coloured bars that appears when the mouse is placend on a side of clip to start the "dragging" action...

this image is taken from a very usual 1920x1080 monitor .. and the green(on cyan) rectangle is barely visible...

i suggest to increase the size of the rectangle (almost to identify if the dragging is "applied" to the left clip or right clip) because a lot of time is easy to start dragging the wrong clip...
