It would be a critical and fundamental improvement to the usability of Data tab on the Item Details page if a user could filter, search and query a layers data from here. Currently this feature is GREAT, but falls short of any intended workflow outside of feature layers with more than 25 or so records. Currently there is no way to actually use it on large layers. Either make the Data tab have the ability to search, filter and query, or bring the edit ability to the Attribute Table widget in Web App Builder (which I believe is a current Idea on the site). This is currently a top improvement wish of our users outside of having the ability to dock or move the pop-up in a Web App.... hint... hint...
