Has anyone found a way to control the position the Slate? 
OpenSlate() has no parameters for X.Y,Width,Height.

PopUpSelectPosition() only works with elements.  I want to use the OpenSlate to provide some feedback to the user, but I want to control its position so that it is not covering up the area it may be referencing.

It would also be good to toggle visibility of the Slate.

Hmm, sometimes it helps just to talk out an issue.  I think that I just solved the problem.  With version 2x I can use @RunWindow() instead of OpenSlate().  I can add a widget element to be used as a memo pad and write to that widget instead of using WriteLn.

Thanks for listening and helping.  And the answer came back so fast, this is truly an amazing forum!

Hmmm, may not work as I intended.  Just remembered that RunWindow dialog windows are Modal.  I will need to close them to continue, vs. my thought of having the Slate opened on the side, like a dynamic Help Screen.  Got some more work to do on this to find a sensible solution.

Looked at @FormAsDialog but found that I can't control its position either.

No, I did not consider that.  Good idea.  Only drawback is that it might disappear if I change tab pages. 

Hmm, maybe not.  No need to put it on a tab, could use any other real estate.  But my tabs are filling most of the screen.  Well, can't tell from here, will have to try it on some application.

Thanks for the suggestion. 
( I am sure the next version will provide positon tools for the Slate.  )
