Disappoint app
App is rather disappointing, advertised as the email app that lets you deal with email the way you need it, high level of customizing options... However, they integrated the link to dozen other apps, but failed to implement basic features like sorting emails by sender. Sorry guys, FAIL!
Their live support is however great (Steven), when I asked about this feature.
