Yalp store
+1 ! If its okay for you, I can make a PR on the Phonesky's README.md and another one on the repository website ( https://github.com/microg/microg.org ) :)
This is not conceptually dead, I just don't have enough time to manage its development and there is no replacement for the concept yet. Yalp Store is a good client for searching, downloading and installing apps from the Play Store, but not a full replacement, as it does not include features like buying, suggestions, push from web store, .... It is a good replacement for the deprecated BlankStore.
@mar-v-in as I suggested in https://github.com/yeriomin/YalpStore/issues/378#issuecomment-382498083 - wouldn't exposing some features of YalpStore (especially licensing verification) would help with the implementation?
