Please stop opening links in a new tab by default in modern pages.

It is against standard web behaviour (https://www.w3.org/TR/2012/NOTE-WCAG20-TECHS-20120103/G200), and is confusing to users when they end up with 10+ tabs open when navigating even the simplest site.

Make it optional by all means, it makes sense in a number of cases, just please not by default.

Please provide the capability to change the header of the new modern pages (i.e. the large banner graphic on which the title is sitting. It currently means page content starts half-way down the screen which isn't the best use of space.

It would be great to be able to target content by Audience (using global audiences and SharePoint groups) on the modern web parts just like we were able on the classic pages. Thanks

The Published date on Modern Site Pages in Classic SharePoint sites is defaulting to US format (MM/DD/YYYY) although the tenant is in AU format (DD/MM/YYYY).

The date format for other content in SharePoint Classic sites is MM/DD/YYYY which is same as Regional Settings.

Consistent with the classic "publishing" use case, would like the ability to add custom columns to modern site pages and make these columns editable in the page properties UI in the Site Pages document library.

An extension of this would allow editing of the page properties on the page itself, similar to custom page layouts on classic publishing pages.

other CMS systems already allow this functionality. Instead of having to save an image somewhere and then upload it to SharePoint, let me just drag / drop images on the wiki and blog pages. Would be ideal for screenshots

Need a way to print modern pages, without the navigation pane etc.

Allow page authors to design page templates right in the Page Edit UI. Page edit would allow them to remove the Title Banner, Logo, left navigation, Edit link, New Link, Share Link, Search box and save the template for reuse.

Page Templates would support web parts and new developed custom JS controls for things like custom navigation controls.

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.

Recycle bin is not relevant for visitors resp. page viewers (users with read permission to the site.) Add the ability to remove it from navigation.

People who wants it can always add it as a standard link to the menu.

In the Modern Experience, allow the option to add "Full-Width Column" webpart. Currently, this is exclusively available for Communication Site template. Would be great to have this available for Team Site template. It does not look aesthetically appealing have this area of white space on the right hand on a site page.

An alert option for leaving comments. At the moment there is no way of finding out if people left a comment.

A user should be able to scroll down seamlessly leaving the chrome bar, any application customizers on top and headings (title and logo) off the screen when in desktop mode. The corporate world would benefit from adding a setting to disable that anchored area since most of the employees are still using 15 inch laptops where the experience is awful if one application customizer is installed on the page. You can see an example in the SharePoint docs issue I created: https://github.com/SharePoint/sp-dev-docs/issues/1284

Blog pages/posts should allow 'Hashtags and @mentions but they currently dont.

The rest of SharePoint social (micro blogging converstations, forum comments etc) make use of this. so it is beyond strange that if you comment on a blog you cant mention someone to make them aware etc

Looks like you can't change columns' width when creating a new section in a Modern Page. Being able to chage it would be very useful. My classic page, for example, has a section containing 3 columns, where the first and last ones have their width set to 25%, while the central one has width set to 50%. In Modern Pages, I can only have 3 columns with the same width, 33% in this case.

Provide better ability to tag pages with labels and content type

When editing text blocks in a modern web pages, I'd like to use the wiki link code [[New Page Here]] and have the same functionality, meaning that when saved I can click the "New Page Here" link and have a new page be created automatically with the original link going to the new page.

Need to have comments and likes for SharePoint News

I'd like to show users documents from an another site (different o365 group site). I came across the Highlighted content web part which is a very flexible and potentially useful function. However I can not filter my documents with it as it
1 does not show custom content type at the type or document type filters (even though my content type is directly inheriting Document), and does not lists my documents either (basically being Documents because of the inheritance)
2 can not select custom columns of my content type at the managed property filter.

I would like to be able to remove the header from the new/modern "Pages". When I add a new page on SharePoint online now, I love the new page except for the top header image and text which takes up about a 3rd of the page. It's wasted space and not aesthetically pleasing.
