Thanks for reminding us of accessibility issues! In the screenshots that
you sent for reference we use red and green lights in two different
places (in the left pane and on the right of "Status") but each time
combined with labels ("On" and "Online"). Do you think that this is
acceptable or would recommend to avoid red and green all the way, even
when combined with labels?
In the case of the left pane for example, when people might have several
services configured, the light *in addition to* the label could help
people who distinguish red and green to parse the status of their
different services a bit faster maybe. Or would you recommend removing
the red and green light in the left pane as well to remove noise for
colorblind people?

segfault: should we use an animation when the service fails to start and
the switch is turned off as a consequence? Is there something to do this
in Gtk already (otherwise we shouldn't bother coding it ourselves I think)?

Yeah, I'm aware of the controversy around these switches...
In the screenshots sent by segfault in the thread "More Tails Server"
the switch is combined with a label for the status, either "Online" when
running, "Offline" when stopped, and some progress indicator when
starting or stopping. I think this would solve the "status" vs "action"
dilemma.
We're using the default switch from Gtk which is used all over the place
in GNOME and Tails already. So being consistent with their look and
behavior elsewhere we play in our favor.
But still, I agree that, as you are suggesting, trying to use them as
little as possible is also a solution.
Build upon the screenshots of segfault from "More Tails Server", maybe
we could do:
Status: On [Stop]
and Status: Off [Start]
to get rid of the switch.
I'll let segfault decide if he wants to try this out and also clarify if
he encountered any problems around this during his tests already.

What do you mean by "light" here? A light bulb that's on or off?
