Hello,

Thank you for your suggestion to show categories in the message preview window. We have actually done this for the mobile theme. The mobile theme is actually a responsive theme that we have been developing to work on all browsers. It can be used on a desktop in the current released version, MD 20.0.4, however, in MDaemon 21.0.0 there were significant improvements in the functionality available. Once you have installed MDaemon 21.0.0, which is currently available to the beta team and should be available to the general public in the next month or so, please take a look at the mobile theme and let us know what you think.

Thanks,
Arron
