Marlin, the new file browser developed by ammonkey (who's also behind Nautilus elementary) for elementary OS, got two new plugins for Dropbox and Ubuntu One.
This means you can now get a public link or easily access previous revisions in Dropbox or publish/share and synchronize external folders in Ubuntu One using Marlin, just like you can using Nautilus:
Install Marlin and Dropbox / Ubuntu One Plugins
The new plugins, along with Marlin and other experimental packages are available in a new Marlin daily PPA.
Important: this PPA provides unstable packages and should only be used for testing.
If you want to test Marlin as well as the new Ubuntu One / Dropbox plugins in Ubuntu 11.10 Oneiric Ocelot, use the commands below:
sudo add-apt-repository ppa:marlin-devs/marlin-daily
sudo apt-get update
sudo apt-get install marlin marlin-plugin-dropbox marlin-plugin-ubuntuone
Or you can use Glimpse to try it out.
Once installed, you need to enable the new plugins under Settings > Plugins:
And finally, restart Marlin.
If you're not using Ubuntu 11.10, you can get the latest Marlin as well as the new plugins via BZR.
