Pop in to Upload form, for metadata entry and check in, when dropping files in to a library.
The easier we can make it to upload docs with properly managed metadata the more they will adopt our systems rather than finding work arounds. My suggestion is to add a feature to SharePoint out of the box libraries that requires the Upload form to appear for any document dropped in to the library. What I've heard so far is that the ability to drag multiple files gets in the way of this. Well SharePoint can stack forms just like it does in other areas.
Example: I drop 10 files in, my first Upload form pops up and I input my metadata, then click Check-In. That files gets checked in and the next form pops up until I've seen all ten forms.
In this example MS can also include an Apply to All check box to make things even easier. So that in the case where my metadata is identical for all 10 files I would update the first form, click the check box to Apply to All, then instead of working the other 9 forms SP would update all with the same metadata and check them all in.
I think it's a simple solution to a widespread problem that, I think, a lot of you are having.
I agree this is a huge flaw with SP libs. Further, if I require a field in a list, user cannot submit until they add that required field. If I add a required field in a library, the user can upload without entering the required field. Why even have required fields?
SharePoint has been broken for over ten years because of this stupid behavior.
That is a good suggestion, as people drop files in SharePoint without any metadata. This will help eliminate that all together! I think training or a job aid needs to be created on this though. Does the pop-up box require the user to click on the "check-in" option? If the user does not check-in the document, it cannot be viewed by others and would be invisible from what I've experienced.
