after hidden/shown once, suggest panel can't be dragged around or closed from the panel header and 'close' button

[nobodxbodon]

and it can only be hidden/shown from the toolbar button

[nobodxbodon]

does NOT work:
reset attribute:
recPanel.setAttribute("noautohide", "true");
recPanel.setAttribute("titlebar", "normal");
recPanel.setAttribute("backdrag", "true");

use Anchor:

1. var toolbarButton = document.getElementById("custom-button-1");
   recPanel.openPopup(toolbarButton, "before_end", 60, 80, false, false);
2. recPanel.openPopup(document.documentElement, "before_end", 60, 80, false, false);

replace id by class, and use getElementsByClassName accordingly

changing id everytime

Conclusion: needs to create new panel every time, and save & load the last suggestion if needed
