Tried it, compression is worse compared to 7-Zip-zstd by mcmilk for zstd, for same speed. The removal of text from toolbar icons is enough for me to never use it again. 7zip can change file associations directly with it and very easy. Feels like NanaZip is worse in QoL than 7zip.

Thanks! Any ideas why it didn't get merged? Clearly 7-Zip has some development activity going on and so does this fork...

Working with Igor Pavlov, the creator of 7-zip, does not seem very straightforward (understatement).

7-zip's development is very cathedral. Igor Pavlov doesn't look like he accepts contributions from the public.
