Koala DC is a client for the Direct Connect protocol. Direct Connect allows you to share files over the Internet (or intranet) without restrictions or limits. It works with DC, DC++, and other DC clients. It has a flexible GUI and multihub connections: it can connect to more than one hub at a time. It features low-level socket connections visibility and the possibility to automatically start up three hubs. It also includes the ability to get small files (and user lists) without having to wait for a slot and without having to wait for larger queued files. It has no banners and no hidden additions such as spyware.

Version 0.4 features a Favorites page in Public Hub List window, toolbar with active Hubs and Private Message windows and various bug fixes.
