//Script to re-render page with context title 'test<some number>-'. See {{tl|test-mode}} for why this is useful.
//Script by Bawolff, feel free to ask if you have any questions.

//To install add importScript('User:Bawolff/test-mode.js') to [[special:mypage/monobook.js]] (replace monobook with skin if you use different skin).

//Known issue: <source> tags don't work (since they add css to head, which doesn't get picked up). Perhaps fixed on next wmf update.
// Only works on vector and monobook. YMMV on other skins.
//could have better support for edit mode.
