This suggestion is a "would be nice to have" and (I think) fairly easy to implement…
With so many excellent plugins it is quite hard to remember what they are for and what they do. Some plugins come with a brief description of their features so members can see at a glance in their plugins overview what the plugin is for. But most only contain nothing but the version number and the author as a description.
It would be nice to include a plugin features description and two more types of information: a) if the plugin requires other plugins or is an extension thereof and b) if there are more adjustments needed than just putting the plugin into the folder (this can be just a sign like (!) or something and does not have to be a full installation description, anything that says: pay attention to this one. Would be a HUGE time saver!)
