Thread:Wishlist -UI (1)

This is my wish-list for UI improvements. (they are all very low priority)
 * When hovering over ANY part of the Signature line (including the blank space to the right of it) all the blue links (but only the blue ones) are hilighted. It would be nice to have each link hilight on hover.
 * When replying to a message the edit box is indented to the level of the message you are replying to. Besides looking ugly, this can become problematic with deeply nested threads, particularly if you have added buttons through monobook.js.
 * Shouldn't the subject field be on top of the message input box?
 * wouldn't it be useful to auto fill the summary field with something like "phsi replies to mackiwg RE: Some Thread Subject" when replying to a thread.
