I'm using this right now on a work trip. Since I don't want to use my work computer for personal stuff, I carry a small bag that has a mouse, small keyboard, USB-C hub, and USB-C to HDMI cable. I set that up while I'm in my hotel room and use my Fold7 as a personal laptop. The items mentioned are all kept neatly in that small bag and it just sits at the bottom of my work bag until I want to use them.
I think this type of "they don't care" attitude on any type of engineering is too simplistic.
Are there engineers who don't care? Probably. Engineers solve the problem given to them within the specifications also given to them. Those ultimately can't come from another engineer but the person implementing the thing implements it to specification. If that specification doesn't include edge cases then it's literally not their job to implement them.
I think that's a bit flawed. The purpose of lower education is learn how to learn. By the time you get to university is when you apply those skills to really learn.
Tixati is simple in the same way Deluge is simple. Because of this they both lack a lot of the quality of life things out of the box that qBittorrent provides.
