# How the panel knows that the window on screen belongs to this launcher.
#
# It used to be chrome-app.wonderink.org__-Default, which is the app id
# Chrome derives from an --app URL. Wonder Ink is no longer a Chrome
# window: it is the classroom's own tabbed shell, which tells Wayland its
# app id by naming this desktop entry. Read back from KWin on a running
# session — class=[ekklesia-wonderink], desktopFile=[ekklesia-wonderink] —
# rather than assumed, because a mismatch here is not an error anywhere,
# it is silently two buttons on the panel instead of one.

# One window, and pressing the panel button again brings it forward rather
# than starting a second one. The shell enforces this itself as well: two
# processes on one Chromium profile directory would fight over its lock.
