Bumping this topic, as the wiki has a mention of this feature (and the associated XML tags) on the
XML/Menu page, but doesn't explain them at all, nor should we assume that anything is necessarily apparent to readers. For example, the wiki has the XML tag
<show-time value="1500"/>. Obviously the value is a length of something in milliseconds, but what? This could be said for many of the new XML and language file tags. Simply giving a short description on what exactly they modify by
editing the page would aid modders in tweaking such values (it may seem plain as day to those who programmed the feature, but not necessarily for the casual translator just looking for the right value to modify so their's enough time to read the text.
