If someone decides they want to install CFW on their WiiU, why would they download the CBHC App and start running it without knowing anything about CBHC, and without reading any of the many guides online?
If a person does that, without any knowledge of how CBHC works, without reading a guide, then honestly that person deserves a Brick if you ask me.
Its not like its hard to install CBHC. As long as you can follow simple directions, you can install CBHC without bricking your WiiU. I got my 9 year old son to follow Kafluke's Noob Guide (I think it was his noob guide), and he did everything by himself, all I did was buy the DS Game with my Credit Card when he told me to. If a 9 year old can do it, anyone can. You just can't be lazy, like 99% of the people that bricked their console.
The point is, don't mess around with things you have no idea what they are for. If your not sure what the app does or how it works, then don't touch it. Do your research first.
And all modders know this, because honestly, this should be common sense by now. When it comes to modding any console, if you don't do your research, then your just asking for problems.
Homebrew Launcher and the main homebrew apps are perfectly fine. Can they be better? Of course. But to add little things you listed in your post, I rather them add features to the homebrew apps that add more features to the CFW. Things that benefit everyone, not just the lazy people that don't like reading. Just remember, all this homebrew we have, is all free, the devs work on these homebrew apps in their free time as a hobby or passion.
