Lock Tag Panel

I propose a simple addition of option for locking the Tag Panel [especially when it's floating] and of all other elements than can be moved around

I have my Tag Panel placed in such out-of-the-box-thinkig way [for the purpose of squeezing into it as many info as possible], that sometimes I accidentally click in a wrong place- and then it gets so rearranged that I have to restore all my settings, because it's quicker that way. And that's a drag
