2. Ok. Two suggestions:
2a. Make it a chain-link type icon. I think that's perhaps more universal?
2b. One should be able to get the URL underlying it from the contextual menu "copy link" just like a regular hyperlink. I often have changes pending when I find something I want to permalink, and with the original Permalink, I can easily copy that link without having to save changes first.
2c. The original Permalink at the bottom of the map didn't really take up that much space...
3. Yeah, I figured as much.
5. Yes, it is there, but I was kinda thinking something would be hiding behind there as there was with the "WazeBar" title.
No biggee. Really not necessary, actually.
