We should add a half diamond arrow on top of the HUD panels in Firelight (site identity, bookmark information). Attached is a rough mockup, this is similar to the contextual menu on dock items, but with the HUD appearance. The windows counterpart to this is bug 413059, where there is an example patch using SVG instead of -moz-border-image, which might be worth taking a look at. Since we don't have to worry about adapting the appearance of the panel for different OS themes, that approach might be overkill.

I'm not really sure yet if we should really use that gradient at the top of the panel; unlike all the other HUD panels in OS X, our panels don't have a real titlebar. Moreover, the gradient collides with the bookmarks bar gradient in a weird way.

>I'm not really sure yet if we should really use that gradient at the top of the >panel Yeah I agree, these will work better without the title bar gradient.

This of course is going to completely fail if the window is near the edge of the screen, no?

Oh, yeah... but these panels pop up towards the center of the window, so it's only an issue if the window overlaps the edges of the screen, right?

>This of course is going to completely fail if the window is near the edge of >the screen, no? Is there any way to remove the arrow in the case that the panel is being draw in a different position to avoid being drawn off screen? Ideally we could add all sorts of extra logic so we could get the arrow in a variety of positions, like when you right click on a link and say "bookmark this link." But that is of course some significant scope creep.

Comment on attachment 346041 [details] [diff] [review] v1.1, image included a191=beltzner - please test thoroughly after landing and be ready to back out if, as Enn warns, the edge cases overtake the value of this patch.

Yeah, so the attached screenshot shows behavior when the window is close enough to the bottom of the screen that there isn't enough room to keep the HUD panel at the bottom of the button.

A bug has been created for this issue with a better screenshot attached to the bug.
