Interface / Ergonomics detail when adding a cell instance

Hello,
I have a request for the ergonomics of the interface when adding a cell instance: I would like that the button "Show all cells" be on the north, above the cell list, rather than below the cell list. The reason is the following:

• After clicking on "Instance > Object Editor Options > ...", the "Select Cell" window opens under the mouse cursor, with the north of the window under the mouse cursor.
• I often have a long list of cells and I often want to unselect the "Show all cells" button.
• But this choice-button is at the bottom of the window... There would be less mouse travel if the "Show all cells" button was above the cell list (instead of below).

Can you consider this suggestion?
Best regards,
Olivier
