Hello again Mojeek!
First bit of feedback is a straight-up bug: once I’ve made a focus, if I try to delete it, the button to cancel works, but the button to confirm does nothing. I click “OK” repeatedly until I give up and cancel. So the only way I can delete a focus seems to be to wipe my cookies?
The second is, I think the focusses would probably be a bit more useful if you could add partial URLs rather than just domains.
E.g., if I search for Test and apply the Dictionaries focus, the top result is a list of challenging words to use in tests (or something) from Merriam-Webster. The third result is the actual definition of the word “test” from Merriam-Webster.
So, if the purpose of the Dictionaries focus is to return some actual definitions for your search term, I think it would be more powerful if you could add .merriam-webster.com/dictionary/ to the list of sites, rather than just .merriam-webster.com. It would just mean you can be more specific and selective.
