I realise the summary is very clumsy, but it's the only description I can think of for what I'm requesting. Recently English Wikipedia has been hit by a vandal that vandalises the day's featured article by not putting penis images not on the article itself, but by putting them within <includeonly> ... </includeonly> tags in templates transcluded onto the article. What I propose is: Please add an extra feature to show a template as it appears when transcluded; ideally the feature would be able to show the template both when transcluded and when substituted. This extra view of the template could be accessible via a new tab next to the "history" link. Advantage of this enhancement: It would be a quick way to check whether a template has suspicious includeonly stuff/breakage. This is useful for not only combatting sneaky vandalism but also for people doing template editing to inspect their work for breakage.
Hi Leung, I just have read your request for the first time. This feature was actually implemented a couple of versions back (can't remember when exactly). Now when you edit a template you have a field at the bottom "Preview page with this template" that gives you the possibility to see the template in action.
