Add new option – Copy screen – Copy other launchers icons layout or settings. Easily copy other launchers icons layout to replace the current one on LL and select his old launcher (if have more than one). For example (from Nova, Apex, Next, Go, miui, trebuchet, etc.)

I mean take items (from old launcher) from 1) normal screen and copy to LL to desktop (home desktop with more screens), 2) dockbar and copy to LL to panel.
