Edit: The list is now saved as .ajoin so you don't accidently lose any channels you have saved.
There is now a Key option. I'm pretty sure you know what this is for. I realized shortly after posting that I couldn't join a channel because of the key :\
Each file is saved as $+ $network $+ .ajoin (Thanks Gummo! :D) so you can use it for multiple servers. I'm thinking about adding an Open/Load button so you can edit another servers channel list without actually connecting to that server. (Keyword: thinking :P)
Still working on it. Still looking for any comments/ideas :D
