There are no "trifles", there are "details", that's all you need about the author's mindset. There are plenty of hard work and hours of polishing behind every feature that seems easy on the surface.
Rapid Product Development
Current version of the product took me about 3-4 months, 12 hours a day on average. Most of this time were invested into experiments with interface design, optimizing algorithms and polishing usability. You can imagine what will happen with the product in a year... or in the next 5-10 years.
I don't like to announce features, but just be sure that backlog of great ideas is enough to keep me busy until the end of my life :)
I immediately implement user-generated ideas, keeping product simple and straightforward at the same time. All bugs get fixed immediately due to the built-in automatic bug reporting system. You may not even notice it, but when you occasionally face a bug report, you will never see it again.
