Neebly IRC Client is a nice tool designed to help you connect with your favorite IRC channels and get in touch with your online friends. Neebly automatically recognizes URLs and gives them browser-like behavior. When typing in a channel's textbox, by pressing tab the auto-completion popup will appear and show all nicknames that start with the typed keyword. The idle time of any user is always available in the /whois information. If you accidentally paste multiple lines in Neebly's textbox, it grows and shows everything that has been pasted before sending it to the servers.
