[Suggestion 14][Remove Inactive Detach Chart Icon for Single Chart]

Hi,

1. When at least two charts are open, each chart has an active "Detach chart" icon, which is okay. 

2. However, when only one chart is open, the "Detach chart" icon remains visible, but inactive (displayed with a dimmed color). 

    This seems unnecessary in this context since it cannot be used.

3. I suggest that, when only one chart is open, the “Detach chart” icon should be removed / hidden entirely to maintain a cleaner and more intuitive interface.

4. What do you think about this suggestion ?

Thank you !
