Levelbuddy - new multibox software for WoW

[sharpMouse]

The one big problem I had was that typing a chat message would, almost half of the time, cause the two slaves to get stuck in the chat box

You can add ENTER key to black list. The minions will not open chat at all. Another solution is to pause broadcasting via hotkey.

Anyone know how to exclude/blacklist mousewheel up/down?

You cannot exclude it yet, but this is second feature in the list

How difficult it would be to change the keys sent by the mouse click features?

Relatively difficult - I do not want to bother people with keybinding. However sometimes I think how can I add keybindings and do not make interface more difficult.
