it would be very usful if an "install" button will be added below "download" botton for plugins and themes in wordpress.org pages.
for example google finds this page for "wordpress cache plugin":
http://wordpress.org/extend/plugins/wp-super-cache
my desired button should goes to:
http://my-domain.com/wp-admin/plugin-install.php?tab=plugin-information&plugin=wp-super-cache
so it doesnt need to download and upload the package. the user install plug in directly from his website.
