I may have posted about this before, but don’t see the thread — and am finding this feature freshly vexing.
With nested folders, wouldn’t it make sense to allow searching of all subfolders by searching within the main folder? Now, if I have a project folder in my main library, I have to either search the subfolders one-by-one, or back up all the way to “Records” and do a library-wide search, which brings up all sorts of non-project-related material.
It seems as if both logic and convenience would argue for structuring search in the way I suggest. (For comparison, in OneNote, whose structure is not unlike Eaglefiler’s, you get the option to search a folder, a “section” (i.e., a folder and the subfolders it comprises), or the whole notebook).
