Either it does not come with a browser installed, or the browser is not added to that launch bar or they changed the browser icon but not the email client icon.
As the email client icon highlights, that icon theming does not make anything more beautiful because a lot of applications do not have an icon which would fit into the theme.
Network adapter selection, charging status and other things which most are not constantly interested in are in the middle of the most important UI element. Put those somewhere so that those are not constantly in my way.
Power button is also right there in the most important UI element. I don't know how others use their machines, but I'm not constantly pressing the power button of my computer. Put it somewhere where other unimportant things belong. And how does a power button, some number thingy and trash can belong to the same area?
Nothing makes sense. Default gnome and KDE are more beautiful and work better. Here's the default Ubuntu desktop https://149366088.v2.pressablecdn.com/wp-content/uploads/202... Browser icon looks like browser icon. Icons are beautiful as their original designer intended. System settings related things like network, battery and power thingies are moved away from the importan things.
