I love how easily you can write your own plugins to highlight code snippets or even entire blocks of text! It's also great that it integrates with Github so it helps me keep track of my open issues and pull requests in real time. There are some bugs when using multiple editors at once - if one editor has unsaved changes, then switching back will sometimes cause all edits from both editors to be lost. This makes sense because this was built originally as an extension for Sublime Text 3, but now supports other platforms too (including VS Code). However, since this is still very new, we're hoping that there won't be many problems down the road. We've been able to solve our problem of not being able to see what else people have changed by highlighting their commits directly within gitlab itself. I like that it's easy to use and it's very flexible. It can be used to manipulate almost any kind of data. The documentation could be better. There are some features that are not well documented. Also, the examples provided by Hightlight.js don't work with all libraries. I'm using it to create interactive charts. I've also been able to add drag-and-drop functionality.
