Hey Glen,
We’ve had this thought too, and even played around with some proof of concepts here – but we’re not happy with the fixed width of the sidebar; some field types literally do not work properly in such a small space.
We’ve also had some initial discussions with the Gutenberg team about this problem. Whilst we can invent some kind of new expanding UI which would handle this, we’d much rather try and get the block editor to consider our use case so all plugins have the ability to handle this case properly.
We’ll have more on this in the coming months as we begin to modernise our block editor experience into a more native feel.
Cheers,
Liam
