Support 0.16.3 breadcrumbs and allow hiding
If you have Obsidian 0.16.3 or above, you can now click its tab title bar "breadcrumbs" to access Quick Explorer (or double-click to open the folder in the built-in File Explorer).
There is now also a Style Settings option you can use to hide the Quick Explorer, such that it does not show in the title bar or status bar. If hidden, Quick Explorer keyboard commands will use the most recently active tab's header breadcrumbs to display its menus (assuming you're on 0.16.3 and the tab title bar is visible).
