The new homepage is very frustrating for the ignored tags: right now the top question on my homepage is about "micronaut", something I don’t know anything about, so I want to ignore the tag but if I hover or click on it I’m only offered to watch it (no!).
Furthermore, the list of ignored tags is very hard to find: you have to click on the cog at the top-right of the "Watched tags" block (ignoring the overlay that says "Watch more tags"), then click on "Ignored tags" at the top of the popin. Even then, you only see the beginning of the list and can’t scroll down to add more:
If you zoom in, the design is confusing: there are more tags to see (but you can’t scroll!), and at the same time you see the "bottom" of the popin with the rounded corners:
The only way I found to circumvent the new useless homepage header is to click on a random tag to go to a page with the previous list layout that shows the ignored tags on the right:
By the way, the new homepage header is totally useless for me and yet it takes ~30% of my vertical screen space when I open the page.
