Just a thought of adding Genres/tags to the topic titles or statistics(or maybe a new section listing them?) in the script marketplace just so downloaders have at least some vague idea of what to expect when they're downloading a script for use.
Guess that's up to the author to put it into the title or the main post. The forum software doesn't have that functionality... It however isn't supposed to be a permanent host for the script marketplace anyway.
I guess it would be more useful to add something like this to the wiki then.
