I like Blender 2.79 - why? Blender 2.79 did not have pie menus shoved EVERYWHERE. In 2.79, there was an option to enable and disable them (emphasis on the disable). I find pie menus exceedingly annoying. (Example: out of habit, I instinctively press Z to toggle to wireframe mode. Instead of getting to wireframe mode, I get this weird pie thing in my face). No one likes pie in their face. I can not find an option anywhere to disable the pie menus in Blender 2.8. Is it possible to disable them in Blender 2.8, or is this a helpful feature we are stuck with?
There is no way to completely remove pie menus (without building your own version) but you can get closer.
Start by disabling Tab for Pie Menu. That will get you back the familiar tab usage.
Next I'd recommend enabling Pie Menu On Drag. That setting makes some buttons (like Tab, ` and others do double duty. Simply pressing them invokes a normal event, but pressing them and moving the mouse makes a pie menu popup).
Now start changing the keybinding in the keymap here is ShiftS Snapping. Set the identifier to "wm.call_menu" and the name to "VIEW3D_MT_snap". Old snapping menu is back.
