Hey

Looks great, I was thinking of doing the same thing, but I have about 200-300 domains - so I would need to categorise them on the "tree".
Probably a bit off topic, but I could not find such pages; what advantages do you see in having your own portfolio page? And why not develop several pages for each domain with context and ads? + link to the specific link?
I am a bit confused because I also wanted to "develop" in this way.
Or do you want to push your portfolio with SEO so that they are more visible in Google?
Best
