Since the localization editors I have come across are tedious to work because they don't allow you to mass edit all entries at once I decided to make my own little editor. It can function the same way as the one used in claymaver's tutorial, but it can also replace text with something else to for instance quickly change a character name in all entries in the file.

How to use:
To open a chunk file click the open button. All the entries from the file will be loaded and their respective hashes and entries will be shown in the list. To edit the value of an entry you can double click it which will open an editor. You can also search for occurrences of certain text in the entry values. To save the file press the save file and export it to your favorite folder.

Mass replacing:
The editor can mass replace the values of all entries in the list without you needing to do it yourself. The replace textbox is the text you want to replace, the with textbox what you want to replace it with. The ignore case flag tells the editor to ignore the case of the text to be replaced. If ignore case is checked the "apply replaced text's case" option is enabled. This tells the editor to ignore case when searching for text to be replaced, but the text that will replace it will have the same case as the original text, character for character. If the replacement text is longer than the original, the out of range characters' case will be the same as the last in range character's case. I.e. if you replace MauL with vader the replacement will be VadER.
