I visually have a canvas of my conversations by email, what I have to answer, what is in progress and what I can answer during the week. If you love trello, you will love Drag.
The most noticeable improvement has been opening my mail and knowing instantly what's going on at a glance, which frees resources in my mind (peace of mind, what a treasure!).
Pros: I finally have a system that I can use that consistently gets better. The ease of use and the ability to make adjustments is extremely helpful.
I stupidly told my co-workers and now I cannot pretent to have missed an email. I have dealt with this to a degree by faining eccentricities but I am not sure how long they will fall for it.
Unprofessional and their customer support was extremely unprofessional.
Sometimes it is in conflict with other add-ons that can cause bugging of Drag, but it does not happen often.
