Preview for usability enhancements to lookups in Unified Interface
We are happy to announce the preview version roll out for usability improvements for lookups in Unified Interface this week. These improvements have largely come from direct feedback we’ve received.
Consistency in lookup entry
Whenever you click on either the magnifying glass or the text box you’re presented with the same list of most recently used records.

To browse a lookup, simply press Enter once the list is there.

Most recently used record type images
The recent list now uses the record type image to help disambiguate between recent records.

Record type selection list
When results span multiple record types, you can now see how many types of records there are and select them from a list.

Try out these the preview usability enhancements and give us feedback at PowerApps Community.
