Works fine so far, just one small nitpick (Switch network button colors should be responsive to theme:)

Nice catch. Will fix this.

Looks good, the only other thing I was thinking is we can also replace the CrossMarginUnsupported with this so we have a single component to handle this across both futures types.

Sounds like a good idea. @platschi do you want to have a more generic component in the new PR or in this PR?

I don't mind updating the cross margin part actually in a separate PR as I have a couple of ideas to improve the state there in general.
