Most of the time I open the files using the Quick Switcher. When I do that, the file opens in the main panel, but I still find it difficult to locate in the File Explorer panel. So if I want to open a file and then create another file in the same directory, I still have to manually dig through the folders in the File Explorer until I remember where the file is located.
Use VSCode as an example. When you open a file with Cmd+P (VSCode equivalent of quick switcher), the explorer panel automatically scrolls to the opened file and highlights it.
I was about to post asking the same feature, many code editors/multi pane programs allows bidirectional linking of panels by use of a toggle button. When linking is toggled, swapping file in editor (for example by folllowing links) always selects the corresponding file in the file explorer (and if necessary expands it’s parents and scrolls to reveal the selection if it’s out of the panel’s viewports’ bounds).
It is super nice when creating a new link for example to just drag and drop the new note in the right place.
