GO SMS Theme Maker plug-in is an Android app developed by Bharath Lakshman. It is a plug-in for GO SMS Pro that allows users to create their own personalized wallpaper, set the font and color, and apply it to the main program as a DIY theme. The app offers dual modes, allowing you to either use an existing template or create wallpaper using free mode. The wallpaper creating function is powerful, allowing you to replace the background image, insert a small image and frame. The wallpaper can be applied to the main program directly, and you can set the font color and size to it. You can also publish your DIY theme so that other users can download it. However, to better use the Theme Maker plug-in, it is recommended to update your GO SMS Pro to version v3.70 or latest. Overall, GO SMS Theme Maker plug-in is a great tool for users who want to add a personal touch to their messaging experience.
