I felt the same way as you when I first saw Pamac v. 6.0. The lack of an app-store was one of the biggest things that drew me to Manjaro from Ubuntu/Mint in the first place. However I held off posting figuring I would give it a fair chance, while I definitely still prefer Pamac 5 it really isn’t that bad and I am sure I’ll get used to it.
I just wish it defaulted to a search box with all packages rather than the accessories menu. A toggle for the pictures would be nice too getting a huge list of brown boxes when searching for libraries is just visual clutter.
That said I have all faith in the Manjaro team and I am interested to see how things continue to develop.
