It looks nice and has “Hygge! 🙂
Here is info about the plugin from Tone Projects. Will be looking into it when its released.

What is Unisum Mastering Compressor?

Unisum is a modern mastering compressor, based on a novel topology that combines classic analog characteristics with digital flexibility. At its core, Unsium is a wideband compressor driven by a flexible multi-band detector (or “multi-band without multi-band” as one of our beta testers put it), affording you extensive control over the attack and release envelopes as well as the transfer curve.

After a year of development and fine-tuning in collaboration with a team of experienced mastering professionals, Unsium delivers transparent, beautiful, and ultra-flexible compression in a class of its own.

We have built a no-compromise, highly tweakable compressor that allows engineers to nail the sweet-spot every time: Whether you want to add glue or groove, shape the dynamic contours, or solve a challenge in the mix, Unisum helps you achieve your goal with precision and integrity.
