It's a great improvement indeed!

I also don't really like it, though, that "Tatoeba" is displayed above the search box. It looks as if "Tatoeba" meant "search" in a language I don't know.

You could include the word “sentence” in the action, like this:

• Limit to sentences
• Exclude sentences
• {action} having translations that match all the following criteria.

Or you could reformulate the whole sentence to something that avoids the problem. You don’t need to stick to the original as much as when translating the Tatoeba corpora. As long as the search option is understandable.

Another translation trouble with the first line of this error message:

"Translate a Esperanto sentence into unknown

There is no result for this search (yet) but you can help us by feeding the corpus with new vocabulary!

Feel free to submit a sentence with the words you were searching."

First of all, I think it's somewhat misleading: I chose from the "show translations in" drop-down option "none". So, the translations are not unknown, I just didn't define the language of the translation. Also, I think the current one sounds strange in English without the word "language", not to mention in Finnish. It would be better if we would't use transifex sting 454 in this case but rather had a new string with words *undefined language* in it.
