Not only is Transcelerator a great program in its own right, it also served to blaze the trail for the creation of Paratext plugins. If you have some programming experience and you use Paratext, at some point you’ve probably thought, “I sure wish Paratext did ___.” Well now you can write your own Paratext plugin and add that missing feature that would make your work easier. If it's something that you think would be generally useful, you might first try sending your idea in using the Make a Suggestion command (on the Paratext Help menu). But if your idea it doesn't fit into their priorities or you know your idea is something that would have more local appeal, it's time to learn about creating your own plugin.
