It already has been announced that we are working on a new theme for Roundcube. This is planned for version 1.4 and is in a very early state. However, we already started implementing some neat features that are nice to have especially when we’re talking about mobile devices support. Here I will show you one of these features.
It is more user friendly and usable especially on mobile to handle recipient addresses as boxes. So, when you enter a recipient it is automatically converted to a box. That element gives possibility to delete it very easily and visually better separates recipients. It also is more compact as it displays only recipient name (full recipient name and address will be displayed in a hover tip).
The implementation uses contentEditable div element for text input. So, this is different from what e.g. Gmail does (it uses textarea element). For now I see no issues with this approach. There’s still a place for style improvements and some alignments, but on a logic side it’s ready for use and I hope users will like it.
In future it could be extended with drag’n’drop support to move recipients between To, Cc, Bcc inputs. Do you have other ideas for this feature?
