This plugin adds a list on the Plugins screen to display only the recent plugins, that means the active plugins and the recently active plugins. 
It also shows this list by default instead of all the plugins. 
It can be useful for developers that have many hundreds of inactive plugins on their development site. It will spare a few seconds every time you go on the Plugins screen.
