Regarding the library web part
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.
We’ve just started rolling out the new list and library web part to modern pages. See this post on TechCommunity. https://techcommunity.microsoft.com/t5/SharePoint-Blog/Introducing-SharePoint-modern-list-library-web-parts/ba-p/64581 If you have specific feedback, we’d love to hear it.
