Personally, the removal of the glyph does not bother me, even with my severe OCD.
I agree there is an issue of clutter in the post auxiliary column, it causes a few issues
- It is blank most of the time which causes our design to appear off-center which bothers the bejesus out of my OCD
- As I scroll around a page "reply as new topic" keep flashing in and out of existence
- It is showing duplicate information.
I actually much prefer the narrower, "stuff is omitted" design (try making your browser window narrow)
Longer term I would like us to get rid of the aux column there, center the design and insert events into the stream for incoming links. That way you will be able to see information about incoming links on narrow browsers and clutter would be reduced.
(if there are more than say 3 incoming links have a "show more button" or something, so 20 incoming links don't cause huge gaps in the stream.
This change would require more extensive design changes, but clinging on to this arrow is not the problem at hand.
People are not seeing the forest from the trees.
