I don’t want the folder hidden on the OS (nor hidden to other apps). In this particular use case (screenshotted by @jacklaing), NotePlan uses the com.microsoft.appcenter and Filters folders for some special app magic. It wouldn’t be able to use those folders if we changed their path.
But even beyond NotePlan, I have files in my folders I don’t want Obsidian to be aware of (they cause clutter and make search results noisy, etc.). But I still want to be able to grab those files easily from e.g., Finder.
