Poor accessibility for new GTK header buttons
GTK3 was pinnacle of usability. The design was very user friendly even for people who weren't tech savvy. Using new apps, the flat UI feels like a bad design choice in terms of UX. The bold text instead of properly indented buttons in header is really awkward, and doesn't scream "I'm a clickable button" for non-techy users.
Please, if there's scope for fixing this, fix it. This feels like GTK's default stylesheet is losing personality. Please do not focus on a minimalist design over user-friendly UI elements.
This is my humble request. I hope there's room for discussion and improvements.
