Navigation improvements

[Tronic]

After creating a new folder, Droppy shows the original folder and it might be difficult to find the newly created folder. It would be more convenient to automatically move into the folder just created (the parent folder is still easily accessible via breadcrumb or back).

Navigating back often doesn't work as expected, especially after performing a search. Search results should be navigated as if it was a folder, allowing next/previous and back to work as expected, within the search result, and taking one back to the search.
