Delete All Entities on Ground

This is something I think many people will find useful. When I play on my freebuild world and I destroy lots of stuff or dig out a large portion to make it flat, my inventory is filled with dirt and stone and thousands of floating objects are left lying on the floor. Also whenever I use /i to get a pickaxe it defaults to 64. When I die this unstacks so if anyone walks over it their inventory instantly fills with pickaxes. I want a plugin where I can type a command and it just deletes all that crap on the floor. I'm sure others do too. If there is already a plugin like this point me to it please

 

WorldEdit could do this with /remove items, or ClearDrops may be able to do it.

 

I'm sure the worldedit thing would work too, but I was looking for something lightweight. ClearDrops is perfect, thanks!
