On kde I can have a bottom bar plus a top bar that is only in the middle not the edges, I like the notch look, only way I can get a top bar in gnome is slightly notched it still goes all the way to the edge. Or I can have no bottom bar and then I can have the top bar centered using gnome to panel, but I like having both. Its just annoying to get exactly right unlike kde, but has more extensions I like right now. Idk, im having issues with extensions not working after reboot, like arcmenu, which i need for gnome to be usable, so far now ive swapped back to plasma.
