When using editor in issues tracker, everything is just fine -- width of editor is more or less equal to the width of resulting text, so when you press
Preview you have a nearly WYSIWYG snap of how your issue / comment will look like.
This isn't that pretty in wiki. Wiki's pages are much wider, but when editing them we're using the very same editor with the very same editing window width. So, pressing
Preview for Wiki pages is actually completely useless -- resulting text will have very different layout than what you see in preview mode.
Can this be fixed? Can Wiki page's editor width be aligned to match actual Wiki page layout and produce a much better WYSIWYG experience?
