Not really sure what you're trying to say. You seem to be suggesting that we make our interface like dcsharp without specifying explicitly what interface features you like about dcsharp besides the sidebar. If it's just the sidebar you want, linuxdcpp can do that: Preferences -> Appearances -> Tab Position -> Left. We're open to suggestions on how we can improve the interface, we just need more concrete examples of what you'd like to see.
