One of those little things that winds up bugging me over and over again. In almost every type of control/indicator I am accustommed to some type of visual clue that a given object is a giver or receiver of data. Usually it is some combination of shading, increment/decrement buttons, something. For Refnums (and DVRs in icon view), there is nothing as you can see from the top two pairs of images.
Open question: Should the terminal in the DVR icon glyph change direction to reflect control/indicator of the DVR itself? I can think about it and say no, but my initial response is always yes.
In the lower two pairs of images I at least change the color to reflect the system control/indicator background defaults. Not bad, but it loses some of the shading effects. Also a bit light against the system default background so a frame may be desirable.
1) Do something (even if it is not exactly what I want).
2) Change the default shading, tweak frames as needed.
3) Fold the opposite corner for indicator.
(Ignore the fact that I was lazy and reflected the entire refnum icon, I suggest only the corner is switched)
Open question #2: while I am at it, why does a VI reference control have an icon which also contains a reference glyph? Seems like a strange Droste effect going on.
