effect presets : yes you can , from the editor just drag the FX to 'all presets' then 'local library' , then do the opposite to load the preset on another profile
complete effect chains : not available from the editor yet, but you can save A to D stomps from the stomp menu & button ( store button, stomp selection )
I wouldn't mind this featuree maybe in a future release G String? I'd like to copy , say the delay block from Performance 1 to Performance 20 just by right clicking copy and paste.
