First of all, congratulations for this great software and sorry for my english.
I suggest to create an optional tab I've seen in other telnet/ssh connection clients, It lies at the bottom of the window and contains several buttons which can be labeled with one or two words. They are configured by the user, so that each time, one of them is click'ed on, the client sends a defined string to the remote host. This is very useful to save time when typing long commands (with many needed modifiers), long pathnames and any other frequently used strings.
Thank you very much.
