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.

I'd like the ability to specify whether items using the Quick Links app open in a new tab or not.

Please allow libraries to be show in List view by default.

I don't mind tile view, but when I got to all the trouble of setting up columns and mandatory fields and it displays tiles by default for each new user, all the power of the document library metadata is hidden.

This happened for me when the library contained only PDFs

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.

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.

The actual Content Search Webpart with targeting audience property is not available for Modern View pages.
This is a great web part functionality that should be preserved in the modern view, is very useful in several item segmentation scenarios.

Improve the photo viewer in an online folder instead of only being able to view one photo at a time. It needs to work much like OneDrive Personal where you can scroll through an entire folder of photo files by clicking a next button.

The quick links web part does not allow mailto protocol based links, and when linking to a document if I have web=0 in the url to force a document to open in the client application, the link is overwritten to also include a web=1. If a parameter exists in a url, the web part should not attempt to overwrite/append it.
