Clicking the "find next" button on the find-replace dialog does not take you to the next instance of whatever it is you want to find. If you cancel the operation and scroll down, the item you were searching for is highlighted--but this can't be the intended procedure, can it?
Also, invoking the find-replace dialog always takes you to the top/beginning of the clip--you can't start anywhere but the top.
Finally, would it be possible to have the "replace all" procedure tell you how many instances were found and replaced?
Note: Original request had two other enhancements, which have been split off into wishlist bug# 287
