did people file bugs on your about not switching to the correct apps page when
/middle/-clicking a "nav dot"?  that seems kind of invalid to me...

There was no bug filed for this. This was one of the occurrences that I found
with search and fixed in the sense that I kept the previous behavior. Do you
think that behavior is not-wanted behavior of listening to the click that was
sent for all buttons?

I think it's fine just to ignore auxiliary clicks for this particular thing.  I
wouldn't expect something useful to happen when middle clicking anywhere on the
page ;)

If I recall correctly there is this little functionality that will be changed.
There is this web store link in the bottom right of the apps page which if you
middle click normally would open the web store in a new tab. I believe removing
this would remove that functionality.

Removed it. I guess if any bug comes up later we can always add listeners.

       this.addEventListener('dblclick', this.onDoubleClick_);
       this.dragWrapper_ = new cr.ui.DragWrapper(this, this);
       this.addEventListener('webkitTransitionEnd', this.onTransitionEnd_);
