Allow custom fields in SharePoint calendar available to view and update from Outlook

Could we please have the ability to create Wikis in SharePoint that look like TechNet or Wikipedia? Please try to make things more simple. Do not over complicate it again.

You cannot copy a site page from on site to the site pages folder of another site. This is crazy. You can't restructure your pages into other sites. This prevents users from investing any effort in configuration that might change. It is extremely limiting.

Provide ability for user to clear frequent sites and activity on their SharePoint page.

We would like the calendar display apps (events and group calendar) to allow a "month" view. We love the events parts and like that they link to a group calendar but would love to visualize this in a month or week format

There is a strong need to Group By more than two levels of column data. Example, we use SP to track mosquitos for vector control. I want to Group by Week, Trap Site, Trap Type, Species, Condition, etc... The ability to drill down and see totals for each condition or "Group By" would be fantastic. This leads to the next suggestion, Add Calculated columns to Group By Totals.

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.

There is too much white space on the new modern pages. I would rather see less white space and be able to adjust the spacing myself.

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.

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 the owners of the sites to view a report of the security of their site. Start by adding a chart of the inheritance breaks of the whole site in one glance. This will become more and more important since you can use the 'Share' button on a file and break inheritance without understanding what you're doing.

Bring back 'export to excel' to the new document library experience

It would be great to tag News posts/articles by category (e.g., training, motivational, announcement, etc.). Users could then refine by category to see all articles under that tag.

include thumbnail of image in events widget card view

SharePoint should support Field-Level permissions. It is very common to need the ability to show/hide field values depending on current user permissions

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.

Add the ability to mass update Content Type using Datasheet view and NOT change the modified date.
