I do, mostly because it gives a different menu if you click that vs the start menu (it shows recently open programs). If I’m searching I generally just hit the windows key and type, but if I’m slouched and reaching for the mouse only it can be helpful. It’s not like it takes up a lot of space, I’ve got an ultrawide at work and dual 2560x1440 monitors at home.
There’s a setting Teams, under “Files and Links” where you can change it from Edge to Default Browser. Scummy that it works that way, but you can work around it at least (for now anyway).
