Indeed, good to see you back Brendan!
On the other question, I find the thesaurus useful as a way of searching for synonyms which aren’t necessarily part of the dictionary definition. You can click on any word in a dictionary entry and go straight to the thesaurus entry and vice versa.
Also, in search, you can use the same ? * # @ characters available in other free search apps but in the knowledge this will only return entries from Chambers.
And “The Word Lover’s Miscellany” is linked in the help menu which is an interesting read!
Have fun!
