Content width for tiled mosaic & few other ideas

I’m using your theme, everything seems to work very fine !

I noticed this :

tiled mosaic are using a fixed width of 500px, which is the default width. It looks a bit narrow of course. I don’t know if it’s a 4.1 specific problem, maybe it’s related to the $content_width var which is not set (saw that here : https://jetpack.me/support/tiled-galleries/)

A Google Analytics option would be nice

The search engine using the full menu width is a good idea, but it’s not always easy to see that you can actually type something. The cursor is at the far left of the menu, its not the first place where the eye is looking. Maybe an animation to show how large is the field would be nice ? It’s just an idea.
