When you add a document library in modern UI to a page as a Web Part, it seems to be showing the library web part in classic UI.
Is there any plan for the UI for library web parts to also become modern in the future?

We would like the library web part to also be shown in modern UI.

The mobile views are not a solution, so many customers turn to custom design, but I would rather a responsive design be built into SharePoint.

Current term set based solution is not usable at all in real life multi site collection scenarios.

The sync limit does not match OneDrive for Business, and adds complexity to the end user experience, administration and architecture of SharePoint. Please remove this sync limit.

Please make the "(+) new document" button from the web part and document libraries match available CTs as the ones available under the "New" button from the Ribbon. Please also include "Document sets" in the available CTs :)

When adding a news article, it would be great to have the option of having a conversation or chat underneath when you post. Thanks!

I would like to be able to preview files without downloading them. Also the site is moving very slowly. Thank you.

Why is this not the case?

In the new web part image of the modern experience, it's impossible to add a link to the image. You should add this possibily, with an option to open "in / out the screen". Without that, it's now impossible now to put a "image / button" to open another page.

After Create a Sites Columns and Site Content Types and add content type to a list with SiteScript, the content Type doesn't appear associate on list setting... because the property "Allow Content Types" is Off, after activate it appears ....

This is a Bug?

Now that Hub Sites are rolling out we might as well have a category for them.

When sharing a Communication Site with external users (activated with Set-SPOSite -Identity https://... -SharingCapability ExternalUserSharingOnly), they dont see the top navigation unless they reduce their browser window size below 1024px. Below 1024px window size the burger menu for mobile viewing shows up.
This is obviously a bug that requires immediate fixing.
Please fix this asap.

Thank you.

Please allow the embedding of RSS feeds within Modern Pages (using the embed webpart)

Whilst the modern pages are improving all the time, with new web parts and layouts, I would like to see web part connections being made available in modern pages. This is extremely useful, especially when creating dashboard pages.

Pages that contain an internal knowledge base it would be nice to show some metadata, like an info Square, where it can show metadata (what process, Customer, Product it applies to) and the rating. Also let the reader rate the page.

Please provide information on what image sizes and ratios will fit best on the Hero Web parts panes.

Traditional calendars are too clunky and users find it difficult to set up a team calendar on their Team Sites - plus there is no intuitive way to embed these in a modern page.

It would be very useful to have a simple Calendar web part - similar to the Events web part - that could be added to a modern page quickly, so that everyone can see each others' activity and schedule team meetings and events more easily.

cards layout for quick links

In SharePoint Online, the site settings option is missing in all the modern pages. It looks weird for all the users as they don't find the direct option to access the site settings page from the landing page of the site. It would be great if you include the site settings option in the modern pages/sites.
