I think the word search should show, like every other app ever, the number of times the word is used and a arrow to jump to the next part where the word is used, not being me the one who has to manually look for where the next highlight word is. It takes a lot of time to find a word.
Also, it should be an option to which proyect do i want to look the word for because otherwise it becomes very messy and not at all useful.
