The idea of pins is that they provide easier access than toolbar favourites or bookmarks.

And if you implement them as part of a browser, then they should work as expected (as per other browsers).

Opera is still crashing for me immediately after playing an embedded YouTube video and has done so for the last few versions under macOS Sierra beta.

I'm currently running Opera v41.0.2349.0 under macOS Sierra v10.12 Beta (16A313a) and the YouTube crashing continues

You "pin" a website tab because it is important to you and you want quick/easy access to it in the future.

However, at present in Opera Developer, "pinned" tabs only apply to the Window they're created in and disappear when the window is closed or when you restart Opera

Please:-
<ol><li>1. make "pinned" tabs permanent,</li>
<li>2. make them show up across all Windows, and</li>
<li>3. have them sync across all the User's devices.</li>
</ol>

FYI: Apple's Safari & Google's Chrome browsers already have this feature where pinned tabs are persistent.

I can also confirm this works on Opera Developer v38.0.2213.0 on a Mac running OS X El Capitan v10.11.5 Beta (15F31a).

Hi There:

Am trialling Opera Developer v38.0.2213.0 on Mac OS X 10.11.5 64-bit ...

Have noticed (with dismay) that "pinned tabs" only apply to the current Window, don't show when you open a new Window, and get lost when you quit out of Opera (unless Opera Preferences are set to "ON Startup - Continue where I left off").

As per Apple's Safari, it would be nice if "pinned tabs" applied to ALL Windows and were permanent (until manually unpinned).
