Ask for optional mods
Have optional mods ask if they should be added or not. A nice message such as the following could be used:
The following mod is optional:
> name: %{filename}
> url: %{fileurl}
> unlocalized name: %{unlocalized}
> author: %{author}
> size: %{size}
> versions: %{versions}
Do you wish to install it? [Y/n/d]
Where Y is default, N is to abort the plugin and finally D is to describe what the plugin does more indepth, if a description is provided.
