Removing +new button possible?

William Smith in my company we frequently have SharePoint lists that we don't want the user to add or edit items from within the list itself, usually because we want them to only see the items they created or are assigned to them.

In this example I have a list where currently only 2 items are "mine":

But instead of going directly to the list to add or edit items I put a Power Apps canvas app on a page on a SharePoint site - it doesn't even need to be the same site as where the list is!

On this page I have added a quick link for the user to create a new item. You can of course omit that if you don't want them to actually create the items, just to view the ones assigned to them. 

If there are columns that you don't want the user to see at all then you could add fields to a Power Apps customised form instead of the default SharePoint form.

The Power Apps app has a gallery that shows only the items where the current user's email is equal to a text column in the list containing the email address. We don't use the Created By or Modified By columns in this case because the person who is dealing with an item might change, so we just have a text column to hold the email address.

The data sources are the list of course and the Office 365 Users connector.

We then filter the gallery to show just "my" items:

Clicking the pen icon on the right of each item opens the edit screen in the app:

The user can save the changes to the form and is then taken back to their list of items in the app. They can now add another item as with the Bahamas entry below or they can make more changes to their items:

And they haven't gone directly into the list, it has all been done from the app and the SharePoint page and they can only see "their" items.
