Before a few days, I wrote a plugin for the opensource webmail, roundcube. I consider roundcube api very well documented and it gives you the opportunity to extend its features. I wanted to upgrade roundcube webmail from version 0.4.2 to 0.8.0 and after this process I wonder what kind of plugins I could add to this fantastic webmail? I went to the repository of the roundcube plugins and I saw with surprise a plugin Drag Upload. I consider this feature very useful. I tried to install this plugin but it was not compatible with roundcubemail 0.8.0.
I thought that I have the source code from this plugin and the documentation of the roundcubemail, why not to try to create a plugin with this feature for the new api of the roundcubemail. I gave it a try and I created the dragndrop_attachments plugin that you can find at github: https://github.com/strimpak/dragndrop_attachments
or at the roundcube plugin repository: http://trac.roundcube.net/wiki/Plugin_Repository
This plugin uses the file api of the html 5 that gives you a lot of space to create beautiful things!
