I agree, in a positive way. It feels fast, no-nonsense UI and takes as little space as possible on your harddrive. Much better than 2000s software where internet connection is a must, UI is as pretty as possible without considerations for the user and often is 200MB for a simple todo list manager.
Yes, and it would be great to keep it that way. But unfortunately, some say there are plans to adopt more "web tech", maybe Electron... I hope that day never comes.
