Is there any mechanism for doing something like the color categories the MS Outlook has? In view of the undesirable behavior of Outlook 2013 I like to move the whole office away from Outlook and to roundcube. However, management relies heavily on color categories and not having them in a mail program is a show stopper.
For those who don't know, color categories are a way to simply mark a message with one colored markers, then be able to filter by these colors later.
This seem doable with IMAP flags.
Any idea? Does roundcube have a feature that could be used for this? Is there a plugin (I haven't found one). Could a plugin be created for something like this?
