Hi, Thank you for your feedback. We have discussed your request, and then we have decided the request feature does not be implemented because it is not realized all settings add on the GUI configuration option. Instead we will support new feature _setup directory_ menu in the next release. A user can easily find the Tera Term configuration directory by using this feature, and then the user can editor the configuration file. Thanks.
I would like to request that EnableLineMode parameter be configurable from the GUI.
