Why did you make this change?

[csilv, 2012/03/13 20:59:49]

FWIW, I like this change. This prevents accidental text selection from clicking
on nav items.  I find this a minor annoyance.

is this necessary? I feel that sometimes people like to click the same thing to
force a reload. For example, clicking a website's logo usually leads to the
homepage. If you're already on the homepage, it is still clickable, and still
navigates to the homepage (effectively reloading).

[csilv, 2012/03/13 20:59:49]

I believe the purpose is to prevent accidental or reduncent page loads. I don't
believe the user would expect this to occur for this use case and there's never
a benefit (unless there's some bug requiting a reload.)

[Dan Beam, 2012/03/13 23:01:45]

That ^ and if we remove indicators that this is clickable (like the hand
cursor), they don't have the same inclination to click it.

[Evan Stade, 2012/03/13 23:08:18]

well, not really --- the decision to click generally comes before the mouse
over. It's a good hint that it's not clickable, but it isn't visible until well
after the user action is actually initiated.
