Refined by surly developer making it more intuitive (12)

I believe the answer is:

userfriendly

I'm a little stuck... Click here to teach me more about this clue!

'making it more intuitive' is the definition.
I can't tell whether this definition defines the answer.

'refined by surly developer' is the wordplay.
'by' says to put letters next to each other.
'developer' is an anagram indicator.
'refined'+'surly'='refinedsurly'
'refinedsurly' with letters rearranged gives 'USERFRIENDLY'.

Can you help me to learn more?

(Another definition for userfriendly that I've seen is " easy to understand".)

I've seen this clue in The Irish Times.
