Is your feature request related to a problem? Please describe.

• In these days, i focused in revit's geometry. It's not convenient when i snoop some geometry object. I can't know where it is from nums.
• I use metric unit in my life. I'm not in the habit of using British system.
• The navigate bar based on listbox, it's not appropriate and needs a new custom control.
• How to improve performance?

Describe the solution you'd like

• Display geometry object in a new window.
• Add unit converter feature to some numerical value.
• New navigate bar or BreadcrumbNavigate.
• Replace datagrid as custom property-grid and use muti-page to improve switch performance.My be it should works.
