Add display directories on two partitioned sides for replication. and Modify file names in batches

[hermitguo]

Thank the author for writing how to use the software, suggest adding two very useful features, especially in the ubuntu system, very lack of these features,

1. Add display directories on two partitioned sides for replication. (eg: total command)
   
2. Modify file names in batches. (eg: total command)
   Press ctrl+a to select all or the list to be modified, and press ctrl+m to display batch file names.
