To keep things organized in Drive and organize documents in a structured way, I came up with the following idea:
A feature that lets me assign categories to files. It should be possible to create these categories and define them with a name and color. This would allow me to define different categories for different topics. With an additional built-in filter function, I could then view the files based on their category.
Personally, this would help me maintain a clear structure in Drive and sort and label the files according to the various topics.
