Community Directory: Focus Explorer - Obsidian Plugin

A while ago I posted Focusing on a Subfolder in an Obsidian Vault, where I hacked together a symlink-based workaround to make the Files pane show only one subfolder. It worked, but it always felt like a detour — so I turned the idea into a proper plugin.

The underlying need isn’t new: “Focus / Hoist a folder in the vault” has been open since 2020 and keeps getting +1s to this day. Focus Explorer is my take on that feature request.

Three ways to enter focus mode:

  • Quick search at the top — the focus bar sits above the tree; click it and start typing to fuzzy-search every folder in the vault, then Enter to focus.
  • Context menu — right-click any folder → Focus.
  • Recent focus list — a history of recently focused folders for one-tap switching back, great for jumping between projects.

Everything stays inside the same vault — no config copies, no symlinks, no second window. Works on both desktop and mobile.

All future updates of the plugin will be posted in this thread.
