The latest feature update brings links to tag listings of an object. There are a variety of tags which will be converted to links: first of all website, url, phone and similar, but also wikipedia, image and wikidata. Finally the “Tag2Link” rules (JOSM also uses this under that name) are imported from Wikidata and OSM Sophox. In some cases there are multiple possible links, which will be presented in a small popup to let you choose an appropriate provider (as you can see in the screenshot for the ‘icao’ tag).
