I made my own Indonesian translation of UT thanks to this tool and your PCK Explorer tool! Thank you so much! Here's my suggestion for this tool: an option to find + replace would be cool, just like Ctrl + H in MS Word.
Regarding Find + Replace, I think that two ways of transferring text to other editors are sufficient for now. Also, the editor currently lacks UndoRedo, so if a mistake is made, it will be impossible to undo the action.
