Clipped filenames on Score page

[UNOSweeper]

The associated filename below each score thumbnail on the (Home tab →) Score page is printed.
If this filename is too long then the filename is clipped and ends with three dots.
Should it be made possible to show the complete filename as soon as the mousepointer is placed on the thumbnail?
There is already an icon to change the overview from thumbnails into a list with filenames. But working with the mouse pointer will be more practical for me.
