I like it a lot.

I also sent a message over the form on your main site to add https://primersion.com/witnesses if you find it suitable.

By the way - did you consider adding a sort of address converter? Meaning you open a page on hive.blog and your favorite interface is @ecency or @dpeak. With a click or even automatically it gets converted to your favorite site.

A sort of asmart rediretc. For example.

https://hive.blog/hive-167922/@ervin-lemark/satoshi-hero-bitcoin-faucet-withdrawal-again-after-five-days
-->
https://ecency.com/hive-167922/@ervin-lemark/satoshi-hero-bitcoin-faucet-withdrawal-again-after-five-days

This can be done easily, I guess?

I know all addresses do not translate to 200. It depends on the filters/tags the interface is usuing. Only general interfaces could be used to be the endpoints, maybe ...

I like the idea. There is something like that called "I love PeakD" which redirects links to PeakD.com.

I think the app store prefers single-purpose browser extensions. We could create a separate browser extension for this solution

Something like the app you mention. Just more universal and configurable...
