Would still like to see Nik Collection 4 fully upgraded/standardized

It feels like it has been ages since the Nik Collection 4 upgrade came out and many of us paid for what I suspect most, in good faith, trusted what would eventually be an upgrade/standardization to the complete collection. I would really like to finally see my investment in the “Collection” be an actual upgrade to the complete collection. Even interface consistencies would be nice and better than what currently exists.
