In the current prototype, the options will only be applied when the
service is (re)started. This allows to simply use text entries whose
values are applied when the service is started. The main reason I want
to change this is that currently it is not clear to the user when the
options will be applied. This is especially problematic if he uses the
persistence feature, configures the service further and restarts Tails
without restarting the service, because then the options will not be
stored and the configuration is lost. This is why I want to use a design
which allows us to apply the options immediately when they are changed.

I think this does not apply, because we would apply the changes
immediately. Given this, I think your option A makes sense if we gray
out the options while the service is running.

I think if we gray out the option and disable the click-functionality
while the service is running, it would be even more confusing without a
signifier. Because then sometimes you can to click on the label to edit
it and sometimes you can't.
Susan and Spencer expressed concern about the unclear state between the
edit action and hitting Enter or focussing anything else. I tried to
address this by creating yet another kind of widget, which is shown in
the attached screenshots. This one also displays an edit-image while in
edit-mode. The user can click on the edit-image, press Enter or focus
anything else - each will apply the change. Pressing Escape will
cancel the edit.

I think this option would be fine, although it's definitely not the
GNOME way.

I implemented a prototype with this option and it looks awful. So I
don't want to follow this further.

I plan to make a very small user test (about 5 people) on Friday to test
the designs A (without any signifier), my new widget, and B.

I already implemented a pop-up to confirm the regeneration of the onion
address. I think this is a

I won't support multiple services of the same type in the beginning.
This is a nice feature for future work, but implementing it would
require a lot of work.
Users could remove the previous service and create a new one. But then
they would lose all of their configuration.

ACK. Do you think a pop-up for confirmation would be sufficient for
those options?
Cheers.
