There's a new experimental feature for the admin app in trunk. When you visit an app's design page, the plugin download button at the bottom links to a page with a list of available contributed plugin packages that will be automagically downloaded and installed for you.
The list of available plugins is provided by the
web2pyslices.com article search api. Warning: The current list is very small and some of the links will not work since the plugin package slice is required to post a direct .w2p archive dowload url.
Note to web2pyslices users: Please update your plugin posts so they specify a link to a .w2p file at the download field. Note also that if you are using Google code as project hosting, they have dropped support for archive downloads.
I think there are lots of missing plugins which were not posted at
web2pyslices.com, so, please, if you want your web2py plugin in the list, fill the following form
