@cassidyjames I've been able to get everything but the spinner implemented so far.

[cassidyjames]

@mmstick awesome! There's a little thing with the icon size and text alignment… I know the Shutdown dialog has the secondary text left-aligned with the primary text, and I think the icon is bigger. Is that something we can do for consistency with existing Shell dialogs?

The spinner is probably fine to skip. The only place I can think of for reference would be the app menu loading spinner on the panel, but if we can't do it easily, I think I can find another acceptable icon.

shutdown dialog for reference

[mmstick]

@cassidyjames I can change the alignment.

[mmstick]

@cassidyjames How's this?

[cassidyjames]

@mmstick it's hard to tell exactly without getting the ruler out, but that looks really close to me. :+1:

[cassidyjames]

@mmstick okay I got out the ruler. Looks like Shell is using 48px icons instead of 64.

[mmstick]

@cassidyjames Yeah, using 48px icons here.
