Save Directory State and restore to that state

### Describe the feature

When doing drag/drop type operations, use Local storage or some other method to save the current state (what folder the person is working in, which folders are expanded, which folders are closed), so that upon refresh to reflect the new location inside a folder, that folder and whatever else was expanded is still expanded.

### It should be implemented because

I am self hosting on a Synology NAS. I see a lot of potential, and I have only been using a few minutes, but it is already frustrating that I want to make 8 files in 3rd tier folder, and I have to keep making Untitled.md files at the root directory, expand folder tier 1, expand folder tier 2, drop the new into folder tier 3, then it refreshes and collapses everything. I then hae to expand folder tier 1, and expand folder tier 2, then expand folder tier 3, to then see the file I am working on and give it a proper name.

I then since I want 8 files in Folder Tier 3, have to repeat that process 7 times. And by the 4th one, I am going maybe this is not far enough along that I should load my content into this, even though it has potential.
