I recently found myself in a need for a basic string editor for instance properties, so I made this plugin. This is a basic text editor like notepad which can load from and save to any string based property.
To load an existing property, open the editor by clicking the plugin toolbar button, select an instance from the explorer, change the property name if needed and click the load button. To save, select one or more instances you want to save the string to and click save.
EDIT: Roblox has been acting up and didn’t let me turn on sales.
