In some scenarios, it can be difficult or tedious to find an item's GUID given its item ID, or vice versa. For instance, if I am browsing a publication in the Docs DXA website, I can easily get a topic's ID from the URL. But from there, if I want to find the topic in the CMS, it's not easy/obvious. What might help is a feature that converts between item IDs and GUIDs, which would allow for easily searching for that topic in question, based on its GUID.
I believe this can be done via the Public Content API, for instance. However, it would be nice to have a faster, more convenient mechanism to instantly do the conversion.
