I agree strongly with this. I find that, as a developer, you often want to move between code, data and UI and being able to easily navigate to a record by ID (or even model) would be very useful.
Example use case: I’ve downloaded all content from DatoCMS and is searching it for something (real case: find invalid usage of quotes it´s instead of it's). The result is a bunch of IDs that I’d like to easily navigate to.
Bonus point if there was an action in your CLI tool for opening the web page. Then you could do things like grep … | parallel datocms ui to open a window for each ID. We do this for another system which has its own cli tool and it is very useful!
