Pretty good, could be better
I like the app, it’s convenient. Some problems that I would like to see fixed:
1. Multiple monitor support is lacking. The app window stays fixed on one monitor even if you clicked the icon on the other monitor.
2. It’s current version of Chrome is outdated. Gmail shows a pop-up message that “your version of Chrome is not supported”. Big issue for an app that was specifically built to open Gmail.
Outside of those issues, it’s a nice way to keep tabs on your Gmail account.
