The Reveal Active File Button plugin adds a convenient button to Obsidian's interface that reveals the location of the currently active file in the File Explorer. This feature provides a quick way to locate and view neighboring files within the same directory. Instead of using the existing command or pane menu option, users can simply click the crosshairs icon to scroll the File Explorer to the active file's position. The plugin enhances workflow efficiency, especially in large vaults or folders with numerous files, where locating a file manually can be tedious. If the file position is not accurate on the first click, a second click ensures the file is correctly highlighted.
