Let's say just like for example like MacOS. It's awesome we have so many tools but at the same time lack of some kind of standardization can seem like nothing works and you get overwhelmed. I'm asking for people that want to support Linux or not so tech-savy people.
I think that the proliferation of software/app centers is a great development when it comes to package management. Guides should mention them as an option to install whatever packages are needed, as a lot of people are clearly afraid of terminals.
Which leads to the “more GUI tools” point, which I'm sure everyone knows by now.
Also, you know how Windows update is so aggressive with getting you to update? That's for a reason.
