How to show element notes in simulation – and general hiding of it, too?

Hello, i browsed a lot but could not find an answer yet:

There can be made a note for every element (and action) this is useful for developement and programming, but:

1) how can i show this note in demo mode? Show, or include in a text- or post-it or ballon-element? best would be by mouse over on specific element.

2) what would be an elegant way to get the following behaviour in demonstration mode:

i want to click one checkbox (let’s call it: “CheckNoteVis”) (or similar) on Start-page or general masterpage to decide if these notes/postits/ballons shall be generally shown or not on all the pages.

my general ideas:

a) every note/postit/balloon on all pages checks if “CheckNoteVis” on Page 1 is checked, only then the elements’ notes become visible on mouseover.

b) simple solution: “CheckNoteVis” steers the visibility of a rectangle on a level on top. This is in a specified area, all notes are placed in the same area on a lower level.

So mouse-over would always show all notes in a ballon (as hopefully solved in question 1) but it becomes invisible when there is a solid white or black rectangle element above it.

Hope ideas are described clear enough. If there are any easier solutions or similar solutions already discussed, please show me where.

Thanks!
