Helpful options for the "Open File" screen
1. Display not only names but also file information. Maybe in one or more columns. It would be good to be able to define the information that is displayed there. For example, if you only want to see file categories, you should be able to set it up, because not everyone wants an overloaded screen.
2. List should be sortable by information type.
3. The list of the most recently opened maps should be as long as you want, or a second list section would simply list all maps that are located in a user-defined location, so that you have a full overview. The update of the list could be done automatically or manually. The updated list would also detect missing map links and provide a visual indicator.
