I have Qlearly which is a regular bookmark keeper. It does a great job when it is up. But, the owner doesn't pay his bills on time and the site goes down for long periods of time. So, if you restart your computer, you can't use Qlearly. He has also promised to add Safari Browser and Mobile but hasn't done it. Even though it has been a few years the product has been on the market.

So, I decided to go with Superdense. Since it is a newer product for me and the owner is very responsive. So, I look forward to many years of use. I love the UI and the ease of use.

One downside is if there isn't a favicon on the website then you get a gray and black question mark. You can hover over it to know what website. But, when I reached out to Steve, he said that those that look like rectangular favicons (Amazon and YouTube)
are actually on a square background. He suggested that I try or hire a developer to help me with this since I am not that tech-savvy to add a favicon to my own website and of course there are products that I use that don't have favicons either and of course I have no control over those sites.

I would like it if there was a way to easily add a custom favicon, so we can know what website we are clicking on since everything is visual without words other than hovering over the question mark.
