You can sort by the record type, which may help. That still doesn’t get to the purpose of the record, though (especially with TXT records, which are used for just about everything). And it does let you search, though you obviously need to know what you’re searching for.
I expect that’s a matter of Claude reusing an existing list widget, one which I complained about here: UI bug - list chunking doesn't persist. And it makes sense to reuse UI elements, but this one has some bugs that I hope will be fixed upstream shortly.
