RaftingWindow & Close Button

I noticed this post is from 4 years ago, now we have the same request as the thread starter. Is it still in the TODO list or already done?

Hello, yes I believe this was implemented.

Actually, I found that I can disable a toolWindow's titlebar now, so the close button also won't show. But when the toolWindow is rafting, other toolWindow can also dock to it, when two ToolWindow docked together and rafting, a very small titlebar will come back and with a close button on it. How can I disable that?  

Hello, if you mean the titlebar that appears when two floating tool windows are docked together side-by-side (or one above the other), sorry but you can't hide that.

Also note that you can just do CanClose and that hides close button while keeping the title bar visible in the normal case.  But this won't affect the other dual docked cased you just mentioned.
