Browser Extensions: As mentioned in my previous blogs when I worked on the ImprovedTube extension - I have recently been invested in learning more about browser extensions. The work I did for Le Git Graph, has taught me about the complexities of integrating with existing web applications (you have to know a lot about GitHub's interface in order to manipulate it!). Working on this extension made realize GitHub's dynamic nature requires me to carefully handle different page states and navigation patterns - and even then, there might be things that change and I'll have to update the code accordingly.
