pitwall v0.2.2

• A hovered machine header in host_sections = "sections" fills the whole row with rounded corners, with its + inside the fill. Its + ends 8dp from the edge, as the content of tab rows and group headers does, and so does a divider's rule when the + is hidden. The + sits in the middle of its own hover square: when an icon button's square and glyph differ by an odd number of pixels, as the header's 20dp square and 13dp + do at 100% scale, the square draws 1px smaller so the glyph has as much room on each side. It sat 1px up and left before.
• In a shared session, the tab prefix's N, and its palette entry, open the tab on the active tab's machine, in that tab's folder there, as the section's + does. They opened it on this machine before. With account profiles set, a tab opened on another machine, from these keys, a section's + or the machine picker, asks which account first, as a tab here does; it took the default account before. A machine with no part of the session yet makes one with a first tab under the default account, so an account other than Default is refused there, in the picker, until that first tab exists.
