Including version numbers and the latest update dates next to each of the individual mods would go a long way to improve any basic usability of your site. There is no efficient means of quickly assessing whether one has the latest version.
You also may want to, perhaps, have the mods, which are listed as new on the main page, directly link to the specific category page within which the respective mod and its download can be located, since there is often no easy way to determine where exactly or which page the mod is located, which is further exacerbated in instances where certain models exist as different mods in more than one category. Even without any such issues, a link/shortcut simply reduces user friction.
Just a couple things that are easily implemented, yet have a large impact. As it currently exists, the user experience is rather suboptimal.
