true docked panel v/s separate window (like vTabs)

Sidewise currently behaves like a separate window... :-(

Can you switch your sidewise UI to an actual docked side-panel (like vTabs?) i.e. chrome-extension://okpnlgbgcfchbicbhjmmhldhkbkfilce/help/help.html)

This is the one thing that's preventing me from moving to Chrome as my primary browser.
