For organisations that would like to use Communication site as their intranet it would be great if you could provision the root site as a Communication site, rather than a team site with a redirect to the communication site.

There is a workaround as mentioned here but i'd prefer a Microsoft supported method https://hangconsult.com/2017/06/29/change-sharepoint-online-root-site-collection-to-use-the-new-communication-site-template/

Including support would be needed.

My client has a legal requirement for using software, intranets that is Bi-Lingual.

Communication sites are really great way to building new Intranets quickly but this is a critical feature for adoption.

In SPO, enable the option of activating SP publishing infrastructure feature in the modern Communication site template/sitecollection.

Please allow site administrators to remove or hide this button as we don't want our internal user to send feedback to microsoft instead of internal support team.

Add News Article Metadata

When adding a news article (site page) on Communication Sites, through the new interface, it would be great to be able to populate additional metadata for the page.

This could be along the lines of tagging pages with keywords for searching through articles or adding custom metadata.

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.

For customers who are trying to completely modernize their large SharePoint implementations, it should be possible to convert an existing site collection to use the communication site template.

It can simply be a powershell command that applies all the features/etc. it needs.

It doesn't need to change existing content, just apply the styles and create the typical landing page for a communication site.

It'll make it easier to adopt upcoming features (like adding sites to hubs, etc.)

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.

Hi! It would be great if you could chose to have the hero web part in lesser height.

SharePoint site news articles are great with the embedded comments section. I would ask and recommend that there be some sort of notifier/alert to the original comment poster when someone else responds to it. This would help keep conversations going forward. It's rather hard to find your original comments when there are many comment posts.

Will the functionality to like/rate pages be added to the modern pages? This is obviously available on classic pages and would be a great addition to the modern pages especially within the Communication sites.

Add the "Rating Settings" to document libraries in Communication Sites. This exists on other doc libraries from other site templates. This would allow users to rate/like content and we could add a section of "most like documents" etc to the page.

Communications sites should not be created in the same managed path as Groups sites. They are not managed the same way and don't follow the same rules.

At least, allow the selection of the path on the create screen.

I like the new Comments feature on Comm. Sites.
But there are use cases, where you need to create plenty of pages without comments. After publishing a new page we need to edit, disable comments and publish this page again.

Would be nice to enable/disable comments by default on Site Collection level.

Highlighted Content Events do not show the event when you click on the event within highlighted content.

News events in highlighted content shows the news article that was originally posted. So why don't events?

The highlighted content event should show the actual event.

Can there be an option to make the Hero Tiles smaller? They are very large and would be good to have some control of the size and how many tiles you can have (5 is too little, I might want 6+ smaller tiles, for example)

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

We are using the communication sites mostly for company news, but we still cant see who read this or that news.

So, considering the objective of a coomunication site, it will be great if we can see:
1. Who has accessed the main page;
2. Which page news they opened;

A ranking for most read news and this kind of thing will also be amazing!

Communication & modern team sites created only in English. There is no option to create them in other languages. Please add language picker to process. Global organizations have local subsidiaries and they wish to allow local teams to communicate in the local language. In the tenant admin you can set option to force default language for all tenant sites or to allow language selection which will be added to the self site creation wizard.
