The "Watches" feature lets you see your code running live as you type it. This means that you can debug your code live while writing it, which leads to considerably less programming errors.

LT has a plugin manager built directly inside of it. This plugin manager connects to LT's own registry of plugins, so whenever you want assistance while writing your HTML, JS, or even Python, just open up the plugin manager, search for it, and click the little install button beside it's name. Your plugin will then be installed.

With LT's inline evaluation, you don't have to re-compile your whole source file. Each time you want to see an output, all you have to do is hover your cursor over the line you'd like to evaluate and press ctrl+enter; LT will evaluate that line of code for you.
