I would like to be able to type //listschematics to see all the stored schematics, also it would be nice if there were an option to default save schematics under a folder named the same as the user who created it eg:
'//save mything' would be stored in 'schematics/iccle/mything.schematic', and corrisponding '//load mything' would search first in my named folder, then in the main schematic folder (or make this configurable via options)

Issue moved: http://redmine.sk89q.com/issues/68

I would like to see a way to load schematics as well.

.schematics are supported. The ticket is asking for some extra features with listing/saving.

I would like the ability to change the folder where schematics are stored using a config setting.

@MoveCraft: Added.

Still have to add the ticket :)
