You can still use the old Explorer: https://wavesexplorer.com
But you are right that the implementation is not good. Unfortunately, the support here does not have a discussion with us (with a few exceptions) and therefore I think that your wishes for improvement will not be implemented. Another possibility would be to discuss this on their other channels like Twitter and Telegram. Maybe they will listen there to that more?

Edit: That is strange. Shortly after posting, I was still able to open the old explorer. But two minutes later not any more. It redirect me to the new one.
On the old page I could still read that feedback via intercom (whatever that is) is possible. So give it a try.
