Hack for button in topright bar in new apps (with css)

Hello, does someone have a hack to put a button our a text or an action in top bar (right) ? Also we try it with CSS but no solution at the moment, maybe someone have already done this ?

I tried put a button in top of the page and put margin-top: -30px; but the button didn’t show, i try put z-index didnt work too.

Like that?

I mean there :

not in pages, only in classic Apps, you can extend top bar, and make an illusion that it is there

But… i see there in page, they have allready coded a column there (css), so why they put nothing ? It would be nice to configure some here.

Pages are still way behind Apps… so maybe a few years more, and you can do that :wink:
