@jancborchardt how about we make the input field a bit wider and put the clipboard-js icon into it, like with the login button on the login screen?

[schiessle]

@ChristophWurst sounds like a good idea. But we should unify this, so that it looks everywhere the same.

[rullzer]

I'm all for it but lets do that separatly against master so we can get this in and backported.

[MorrisJobke]

I tested this and it works fine. I only added a bit more margin between copy icon and "Done" button to have it look nicer.
