I know this is a minor thing Pierre, but would you consider eliminating this IMHO time wasting message (see screenshot)?  I don't think it serves any purpose and unless I am missing something there is no need to protect the user here.  The answer to the prompt is "of course I want to do it for the selected item, that's why I clicked on the selected item and chose mind map!"  

 

Also IQ is capable of having 10 mind maps open at the same time, it's not like the user needs to be warned that the new mind map is going to replace another currently active one, so I don't see any scenario in which this message is necessary?

 

Thanks
