I've yet to find a really detailed tutorial, or a blog post, or thread here about editing panels. It seems pretty simple—unlock, move stuff, lock. But what, for example, is going on when you rearrange elements with the panel unlocked and the panel grows to accommodate, but then when you lock the panel, it goes back to the old size, making your moved items not visible? Seems clear that the panel size needs to be separately adjusted, but it's NOT clear where/how to do that. Any links, suggestions? TIA!
