The FOLDER view ( list- grid or category) does not meet our expectations, as it remains poorly organised. We are looking for a simple structure:

1st page: Main folders (e.g. ESCARDIO, CONGRESS, etc.)
2nd page: First-level subfolders
3rd page: Additional subfolder levels

And so on

In the suggested view, everything appears mixed together, which makes it difficult for us to work efficiently.
We really need a basic hierarchical structure, similar to the folder organisation in Microsoft systems.
