Overall when I was invited to try out the desktop application I was expecting a lot more. than just a stand alone (browser free) version of the existing Webpage. Having a desktop Application should allow a lot more functionality than whats already immediately available. the only difference I see is a slightly better notifications set up. Don't get me wrong i like the new system tray notifications rather than the bulky pop up notifications that come from the browser and chrome extensions.
The main thing i would be looking for in a desktop application for mighty text would be a UI upgrade and integration shortcuts to switch between conversations without needing to click on the tab. mighty text on the desktop should be a way to text with minimal disruptions to a persons workflow. and alt + tabbing to mighty text desktop app is awesome, but then needing to take one hand off of the keyboard to switch conversations is something that gets annoying and could be easily fixed. and would overall make the desktop experience exactly what it should be.
