There are some improvements / fixes needed in focused overlays
1) Position of the action buttons in toolbar: in normal stand buttons should be aligned to the right edge of the toolbar, in collapsed version - occupy the center of the second line.
2) Minimal width of the focus overlay is 320px (phone portrait)
3) Please, take care about the fonts / typografie: compare the labels in Photoshop sketches and the resulting HTML rendering - there are seriou differences in font weights as well as in vertical centering. Different browsers render differently, therefore we'll need some UA-based enhancements here to assure the best quality.
4) Please, control the heights and spaces between lines of toolbar in "small" stand, currently it's too big - see the PS for reference
5) Add "list" icon to the marker for list items
6) Care also about vertical alignement of the "saving status marker" in drop-down.
7) Please, highlight "Page" segment of the breadcrumb (everywhere), because it works slightly different, then the other elements and is, probably, the most important control. I want to have it more "outstanding"
8) Can we somehow assure, that the there will be at least 3 segments of the breadcrumb always visible: the "page" (as the possibility to get back to start), "the direct parent" (as the possibility to get at 1 level up) and the current selection. If there are other segments in between and we don't have enough space, we can collapse them to 5-6px width pointers.
9) Please make the "disabled" grid look darker, as on the screenshots
10) Colors of the target overlays are OK, leave them as now in prototype
