If a TaggedValue of Toolbar=true is set on a ViewModel, toolbar mode is turned on for that ViewModel.

If you set SysMDrivenMiscSettingsSingleton.GlobalToolbarMode=true, all views that do not have the TaggedValue of Toolbar=false will have gotten toolbar mode.

Main design ideas

ActionRenderPosition LeftSide, ContextMenu, ToolBarLeft, ToolBarRight

Two distinct types of actions:

#1 Those that DONTCHANGESTUFF+Navigates-> Stays on leftside,

#2 Others(data changers, even navigating) + save, cancel, Edit(ReadOnlySwitch) goes into new horizontal toolbar below mainmenu

• End in mind : reduce left menu. It will only hold safe, ViewModel-top-level navigations without side effects - as such, it will not blink or act dynamic
• Nesting level actions are only available via context-menu in grid (context menu content will probably also be divided into the 2 types of actions)
• This new style is optional (since adoption is not the same for all projects)
• The ability to find #1 type of actions relies on the new ReadOnly-functionality(that can deduce if action changes data or not)
