MUDDweller supports multiple sessions, connections with either the communication tool-box or with Mac TCP, a command history and simple file transfer mechanisms. In version 1.2, the main window is now re-sizable and supports more than 32K of word-wrapped text in an arbitrary font and size. This version also adds support for logging a session to a file and for simple macros. Macros can be used to automate the login / logout process or to perform a fixed set of operations when a key is pressed.
The author seems to have given up development at version 1.2. Too bad!
