@William Reynish (billreynish) Ok this surprised me. I don't think this is very user friendly. I do get the justification on a surface level but then why wouldn't the options also disappear the moment you create custom shortcuts or change some shortcuts manually. You could change the Blender keymap completely and still have these options available but once you create a new keymap to export it or create a backup, it will deny you these basic options?
To everyone here at the studio this looked like a bug because it seems nonsensical to just remove the settings after a new keymap is created.
Even in 2.79 you still had these options on the side after creating a custom keymap.

Let's say I change a shortcut completely that relates to these options like: Change the mode switching pie menu from Ctrl + Tab to Ctrl + Spacebar. When I toggle the "Tab for Pie Menu" option and "Spacebar Action" it will override any of those changes anyway. Why should that only be an option in the Blender keymap but not a custom one???
If the user doesn't want to use these settings there is an option to close the dropdown of them. Out of sight, out of mind.

@Julien Kaspar (JulienKaspar) We didn't have this concept at all in 2.79 and earlier.

I'm merely pointing out that it's not a bug and that it works as designed. I won't argue with you that it couldn't perhaps work differently or more nicely in some ways, but that's a separate thing.

@Julien Kaspar (JulienKaspar) a trick..
if you want the settings to work also on the custom keymaps, first set the options from blender keymap, then set the customized keymap .. it works ;)

@William Reynish (billreynish)
As long as developers are aware of the issue and it's documented somewhere as a to do I'm ok with that ;)

That deserves it's own bug report :D

I thought you guys said 2.7 keymap will be still supported.... Why do I have to be punished for not wanting to use the 2.8 keymap that is missing quite a bit of keys from the 2.7 one. I dont get why advanced users became second class citizens all over a sudden because u guys decided to make blender more friendly for beginners. I want to have Pie menus in 2.7 keymap too but the only option is the Pie addon which isn't quite like it.

@Likkez (Likkez) the 2.7x keymap is still available. In 2.7x, the pie menus were only available via addons.
