Files doesn't snap to the sides

With the default Ubuntu install you cannot snap Files to the side of the screen on a 1366x768 screen. Since this is a common screen size it is tempting to raise this as a bug, but it isn't a bug in the code. This seems to be as a result of a policy decision. An application won't snap if it cannot be resized to half the screen size, and the minimum width of Files is clearly slightly larger than this.

Adjusting the minimum width by a few pixels would seem to be the best option (that may be subjective). This may, however, be considered also as a side effect of the Ubuntu Dock down the left hand side, which reduces the effective screen width. An alternative fix is to reduce the icon size of the dock from 48 to 46 as this allows enough width for Files to now snap to the sides. Visually there is little difference, but 48 very much feels the right number (icon image sizes, etc.), so unless a more drastic change to 32 makes sense, I would suggest the preferred fix is to adjust Nautilus/Files - other docks used on the side would presumably have similar problems with a commonly used size for larger icons.
