Nice extension! I was looking for an alternative to autolink.
I'm wondering if you might consider adding the option to allow the extension to perform as autolink is supposed to, without needing to create your own list. I know it's an intensive process for the script to run through every page in the database to account for all the possible words to be linked, but I would find it useful for my own personal wikis that I use for productivity purposes (Where performance is a non-issue).
In my wiki (MW 1.19.2) I've installed the version 1.0 but Wiki goes in crash.
Apache log report:
... mod_fcgid: stderr: PHP Parse error: syntax error, unexpected '[' in /home/.../w-it/extensions/WikiPages.php on line 45
