I heard about chum, but had no clue how to use it. At the github page I found a how to: https://github.com/sailfishos-chum/main#how-to-use-these-repositories-users
But this stuff is a bit to match for me. I’m not using a smartphone to handle things using the terminal. 
For me, as for other “usual users”, it would be great/necessary to have a gui. 
Anyway cleaning up the store would be great!! There are some many not working apps!! It’s better to have few working apps than hundreds of not or only 10 % working apps.
