I wonder why devs need to work on multiple different environments. I only have (user)experience with KDE and GNOME but what’s the difference between them?
- It’s not the default layout, you could ship another default version
- goals can be to maximize customizability (features) while minimizing ressources. Or the other way round. (Or simplicity)
- is it because devs like different frameworks (qt, gtk)? Or language?
Yes, that’s the result of it but not the reason
Sure it is, you use what you like, developers develop what they like, Businesses build what they think their users like etc. It just boils down to different tastes and visions.
