Sure, but I thought apt was just that. Anyone can make a repository or app store and give you access to apps thru apt-get install app. You could also run ducker to run virtual apps.
I would want to run gimp, krita, scribus inkscape, blender (maybe), Joplin, python/notebook, Spyder, libre office, etc. I think that would be a great list of apps that already one can easily install via app. I don’t want a store like apple or google and for sure I don’t want black box stuff that will run in the background consuming battery and stealing my data. I’ll go check the review to see if the “it’s not there yet” refers to functionality where these apps will keep crashing vs functionality meaning my mom can pick it up and use it like toddlers do. Big difference for me.
