Some of my most important dashboards I use to run my business are so mission critical that they should be in front of my eyes all day long (like having access to a clock to know what time of the day it is).
My idea is to create a 'Floating Widget' of my Tableau Dashboard, and allow me to place it on my Windows Desktop. Just like a Tableau Dashboard in Tableau Server, it would update with my data. In this sense, when important KPIs of my business change in real time, I'd see it on my Windows Desktop Widget without ever having to access my Tableau Server Dashboard within a browser.
It makes Tableau even more ubiquitous in my business' operations, and gives me real time information in a visible and configurable dashboard widget. Employees responsible for various functions within the organization could have this widget placed on their desktop as well.
