v0.4.11

Direction C, and a light with one meaning

designs/ui-redesign/ held three directions and C — Editor Native — is the one
that was picked, so both clients are drawn from it now rather than from the
system they happened to share: one violet accent for what is chosen or in
control, paper-flat surfaces at 6/10/14px, pills instead of underlines, and the
same near-black terminal sheet in both appearances. The one piece of chrome that
is not words — the light along a shell somebody else is typing into — now means
one thing only.

• Both clients take the C direction. The accent moves from teal to violet:
  0.4.9 had moved the desktop off its violet onto the browser's teal so the two
  would match, and the direction that was then chosen is violet, so both are
  violet now. Tabs are pills on a raised strip instead of underlines, the
  composer is one bordered field that lights around the caret rather than a card
  with three controls in it, the key bar is one row of equal keys grouped by
  hairlines, and the sidebar, the session inspector and the settings window are
  redrawn on the same tokens. Colour means one thing each — accent for chosen,
  amber for read-only, red for gone, grey for exited — and where the desktop
  drew decoration that carried nothing, it draws nothing.
• The terminal's sixteen colours are the app's. The browser client's theme
  and the desktop's carry the same numbers now: the cursor and the ANSI magenta
  are the accent's violet, the selection is that violet at 28%, and the sheet is
  the same #0d0d12 in both appearances. A shell should look like it belongs to
  the window around it, and ANSI's sixteen are drawn for a dark ground — which is
  why the light appearance keeps a dark terminal rather than inverting one.
• The light along a taken shell is drawn under one condition, and it reads as
  light. It used to come on for any shell another client held, including one on
  a machine the person is not sitting at — a light for a process that is
  nobody-here's, which is the ordinary case rather than news. It is drawn only
  for a shell this machine runs with somebody else on its keyboard, which is
  the one thing the words on screen do not say from across the room; a shell on
  another machine keeps its 只读 chip, because that is a fact about the pane you
  are looking at. The effect is one family of colours instead of a spectrum (the
  old cut ran violet, pink, coral and peach around the edge — a second and louder
  vocabulary for a fact the pane was already stating in words) and it is a band
  with no line anywhere in it, falling off on both sides of the pane's edge, the
  way the platform's own agent-takeover glow is drawn, rather than a coloured
  border painted on the pane. Where the desktop asks for less motion the colours
  stop travelling and the light stays.
• The takeover offer says what pressing it does to the other side. The panel
  under a shell that is not yours names the holder, says that your typing is not
  reaching the shell, and now says what happens to them: they go read-only and
  keep watching the terminal afterwards. A button that takes a keyboard away
  from somebody without saying so is one people learn not to press.

Fixed

• 释放控制权 was offered by a window that held nothing. The browser client
  sets hidden on the button, and hidden is a bare display: none from the
  browser's own stylesheet, which loses to any class that sets a display — and
  every control in that client does. The button sat in the header of a window
  with no session at all. The per-class workarounds the stylesheet had
  accumulated (.tf-hero[hidden], .tf-inspect[hidden], …) are one [hidden]
  rule now, so the next control that hides itself stays hidden.
• The browser client's status line went stale after the session list changed,
  counting sessions the sidebar no longer showed, and the session inspector could
  not be closed — the button that dismissed it reopened it on the next render.
  Both follow the person now: the count follows the roster, and whether the
  inspector is open is a choice that is remembered while the page is.
