I am designing this tool now.
This tool will based on Swing.
I designed the actions, used by menu, toolbar, etc., and listed them up.
The properties that you can update at runtime also have been designed.
And some utility classes is being coded.
You can find all these by CVS.
MR. Project, a project to develop a multi-replace tool start now!
The project is planning phase now. Just be patient and you will get a wonderful tool for replacing.
