I personally have never had an issue with it. There are many buttons but they are all very discoverable with a bit of hovering. I vastly prefer it to "modern minimalist" interfaces where I have to drill through 90 layers of Hamburger menus to disable a goddamn notification.

I could write a long list of small quality of life tweaks to its UI.

But, at the same time, I wonder how many HNers have even built a UI for a product with so many features. It's incredibly hard to find a good place for everything. And experimentation is expensive and time consuming.
