dsh-sidebar-enhancement-folder

When you have several files open in dsh-better-sidebar, locating a particular file on disk is more tedious than it should be. The sidebar offers no per-tab shortcut to reveal a file in the system explorer, so you end up copying paths by hand and hunting through folders.

This plugin drops a small folder icon directly into each editor tab toolbar. For Markdown and HTML tabs the button sits beside the Preview and Edit toggle; for PDF, image, or binary viewers it appears in the title bar. The file path is read from that tabs own editorPathInput element, so every button always points to the correct file regardless of which pane is active. A MutationObserver combined with a periodic heartbeat keeps the buttons in sync as you drag tabs, split panes, or resize windows, and prunes any duplicates or orphaned icons. On Windows the click invokes explorer /select with proper quoting for file names containing spaces or CJK characters, and if the original file no longer exists the plugin walks up to the nearest surviving directory.

Built for Windows users of dsh-better-sidebar 0.14 and above who juggle multiple files and frequently need to jump to their disk locations. Please note that this is a personally used, AI-assisted project that has not undergone broad testing; a future better-sidebar release may introduce breakage, so install at your own risk.
