You made it very nice, if you want, it can be made beautiful by someone. Since you have made such a tool where many sources can be found together. I want to tell you one more thing as a new one, that is, this tool has many more important guidelines within it, if you can add them, then the thing will become more beautiful. I shared this with you as my personal opinion, you can do it if you want.
Hey there OP, I just realized the dark mode on your site isn't fully dark. I thought it would be like Pitch black themed dark, but it isn't. The current one only covers a portion of the site. So my suggestion would be make it complete pure dark. That would look better to the eyes! Just my two cents, of course...apart from that, everything else works out for me perfectly.
I think the OP did not think much about it, that is why it did not give so much importance to the dark mode. However, it could have been made a little more beautiful if the whole thing was made in dark mood and the sectors could have been given a different coloring shape. Maybe he has plans to make the design more beautiful with it in the future. Let's see what he does in the future.
