A OOTB feature should be available to hide "Shared with Us" link. Also, a suggestion regarding the placement of this link.
Can we have this link on the document library ribbon menu instead of Left navigation menu.

Currently you need to paste a URL in a MLTB but if someone is looking to clip and paste a image from their PC, this become a pain. Can we please just paste directly into the MLTB?

Add a photowebpart that shows the content of a picture library in thumbnails. when you click a thumbnail, a popup will appear with the photo in a "normal size" (as available in _w hidden folder) and than you can browse the photos with next/previous buttons, with an option To show the picture in original size.

There is currently a 255 character restriction on Hyperlink fields. This restriction impedes ability to save Urls that might include hash values are long query strings. Some examples where this is really common are links to SSRS reports (with parameters) and Search urls that contain refinements.

Content types are an essential part of SharePoint. One issue that has been around since SharePoint 2007 is the absence of an overview of all applied content types. Why is this important? Try to delete a content type and you get the message it's still in use. Good luck finding out where. This is very frustrating and time consuming. That's why I vote for an overview where you can see where the content types are applied.

SharePoint Online. We really need to set some restrictions of file types that user can upload to a document library.
For example, to deny upload file with extension .bmp and .tiff.

Don't think this has been suggested yet, but Hub sites should definitely allow nesting!! The flat/flexible organization is good, and allowing some hierarchy/rollup with hubs is better, but would be best if a hub could be a sub of another hub (a branch, sub of region, sub of district) and have rollup through each level of nested hubs. Allows best of both worlds - flexibility of flat and dynamic association, with advantages of multi-layer hubs!

In the new experience, our users still want: 1) to check-in multiple files; 2) open .msg and .pdf files in their client application without having to download it; and 3) in the viewer while looking at a pdf file with an electronic signature, the signature disappears; we'd like to see the signature please.

Provide an editable field for publish date of pages and news articles. As we migrate content from another platform it's important to maintain existing "published" dates

Security trim the hub site's top menu bar

My users would like the ability to publish a modern page on a given time. Now it is only possible to publish a page directly. Make it possible to publish a modern page on time the user (optionally) enters in a datetime field.

It would be nice to have the option to place a web part on a modern page and add HTML to it. We don't always want to jump to SPFx for something simple. It would help add some flexibility to the modern pages.

Back in September, we have used below columns to extract picture/image metadata w.r.t location in SharePoint Online:

wicSystemGPSLatitude
wicSystemGPSLongitude

It worked brilliantly. But unfortunately the functionality doesn't seem to work anymore.

Other metadata such as date taken has also been removed. This is causing extreme headache for customers who relied on this data.

PLEASE BRING THIS BACK!!!

Open ".xdw" file in browser without downloading it

".xdw" 形式のファイルなどをドキュメント ライブラリに保存した際、ブラウザーから開く際にはダウンロードされてから開く動作となる。関連するアプリケーションと関連付けを行う機能等により、".xdw" 形式のファイルなどを直接ブラウザーで表示が可能とする機能の実装を希望。

When we try to open ".xdw" format files stored in document library, we first have to download it to open up. What I would like to happen is for the file to simply be displayed in the browser without downloading it.

Thank you for your consideration.

Categorize and filter news articles on new publishing site
Ability to select category (or multiple) for a news article when you create it. Plus the ability to filter the news widget by category.
Exactly like you can for events. Plus the ability to select multiple categories if you choose.

Please provide option to customize email templates used to send notifications out of SharePoint online like "Send by Email" feature on modern UI pages, sharing notifications to other users. Most organizations do not allow users to install mobile apps. Providing information that is not approved will confuse the users and require constant training.

Allow to display filename attribute instead of title in Highlighted content webpart

Office 365 Connectors within SharePoint are only available for use within group-connected SharePoint team sites, according to https://support.office.com/en-ie/article/use-the-connector-web-part-db0756aa-f78f-4b74-8b19-be5dca0420e1.

Please add support for using Office 365 Connectors also in Communication Sites. For example, I would like to display data from outside by using an RSS Feed connector on a Communication Site page.
