Add the functionality to search and open folders.

[Kiss-World]

The current features are very useful, but sometimes we don't want to directly create folders or files; instead, we want to locate the folder, observe the file structure and the contents within the folder. So when the corresponding folder appears in the search bar, an option can be added to locate the folder in the list and expand it. This, combined with the official feature of creating notes in the folder where the file is located, may make it even more user-friendly
