As you may have heard, the Roundcube team is developing a new skin called Elastic. The skin will be responsive and will be usable on desktop devices, tablets and phones. It's still in the works and it will take some time before it's released, but we'd like our plugins to be fully compatible with Elastic as soon as it's ready. We started upgrading the plugins to make sure they work with both the current Larry skin, the Roundcube Plus skins and the new Elastic skin.
It will take some creative work to make sure the plugins are versitile enough to work with all the skin variations our curstomers would like to use, but the work is going well, and we're confident we'll have the plugins ready by the time Elastic is released.
Here are some development screenshots:
