Filters are also needed for customizations, apparently people just have trouble finding the options they are looking for the more mods are added. Maybe that is because they are not familiar with the sorting, but this could also be trouble for new users as well that start developing and could pose an initial barrier.
my take: Make the options on the right side easier to expand, by putting the expansion triangle on the left instead of the right. That would make life much easier!
