Currently there is no way to exclusive work on a list-item. In document libraries the checkin/checkout feature can be used to prevent mulitple users from update a certain item.

When I'm update listitems in code, I have to make sure, that no-one else is currently updating the item while I change some data.

Potentially someone could update the item while I'm also update the item. Whoever save the item last will receive an error. This could be prevented with some kind of locking of list-items.

By default, if you do perform a CAML query and there are more than 5000 items in the list (although the results are far less), it throws an exception. Please fix this.

move documents from one library to another

New Document Library’s Top Navigation menu is all jumbled up and not showing all the links. There is also no drop-down menus like in the Old Classic Document Library.

Make it possible to use file explorer versus the list that appears. Dropping files takes to much time. I have to use my desktop now as a stopping place where I never did that with my actual server.

Enable css (branding) and ux components (like global nav) to be globally deployed in the tenant. It could be a setting in the administration that could enables this option to allow custom js or Css to be injected across over office 365. With custom actions or alternate css or whatever to make a unified experience for customers which are in a great need of having their identity in their digital workplace.

Need to be able to upload OneDrive Files to Groups.

ik mis in de nieuwe weergave de mogelijkheid om via de bibliotheek een map te openen met de verkenner. Voor mij dus niet werkbaar deze nieuwe weergave.

Need a way to attach documents from Sharepoint online to Outlook app or Mail Online, either drag and drop or right click "attach to Outlook"

Please fix infinite scroll. As the items load, the scroll bar will repeatedly pop back to the top of the list, making items lower on the page difficult to access.

Can't seem to find the "open in explorer", library settings and edit View options in the new SharePoint library experience. Appears that the new Library options are very limited/restricted. Please bring back the Ribbon with all the commands to the new SharePoint library experience... :(

We need to be able to share folders with external users without the need to sign-in, but are unable to do so at this time. Please let me know when this is fixed.

Uploading - is there a way to upload multiple folders??

I hate the new look for my personal page on SharePoint. I would like it to be consistent with other features of SharePoint, e.g. like promoted links. I would like to set my page to be the classic look before what it changed today.

Can we please have the Document Preview back when the ellipses are clicked? It was so easy and the document link was right there.

Now we have to select the document and then hit the information button which gives us not so useful information. Then if you want to copy and send the link to someone you need to click "Get Link" and select which type of link. Not a fan of the new UI. I don't see a win for anyone with the new UI.

Tick items to share in library list then use standard share options.

A multi-file download button would be great!

Please add a document preview or "instant access" so i dont have to either download or open each document in a new tab to check it's contents.

When using managed navigation it's not possible to use the column filters.

See: https://social.msdn.microsoft.com/Forums/sharepoint/en-US/ab5c7d15-14e7-470a-8120-71d049a104d3/list-metadata-navigation-and-columns-filters-not-working?forum=sharepointgeneral

The "workaround" to use server rendering in the webpart properties isn't really satisfying, cause you lose features like list search and multi-value filtering for choice fields.
