Lead dev of email client Decco, Daniel Wood, has shared some images from the development version of the software, and they look stunning. Images are taken from different form factors and it seems that convergence is the top priority. Check out the gallery (you will need a Google Plus account).
Dekko received an update almost after 1.5 years and the time seems to be well utilized.
To install Dekko on Ubuntu desktop releases from 15.04 to 16.04, run:
$ sudo add-apt-repository ppa:dpniel/dekko $ sudo apt-get update $ sudo apt-get install dekko
