When you mod for a long time (it's been 5 years for me), you will probably, just like me, make multiple modlists, for several reasons. When you build heavy modlists (i have 1400+ mods), and you want to make a new one, it's really a pain to know which one you downloaded for that new list or not.
For those reasons i would really appreciate if you can work on a way to permanently hide that download history.
