Peacock – Late Night Coding FTW


A while back I created a theme for VS Code called Winter is Coming. I learned how to do this by reading this great guide on theming in the VS Code docs. I still use it today (I love the dark versions). It taught me a lot about how to customize colors in VS Code. I then started using this to help solve another problem I had: quickly and visually differentiating between VS Code instances
I’m often working on multiple code projects an articles I am writing in markdown. My worflow is to open different separate VS Code instances for each, as they are often unrelated to each other. As my mind shifts between the work, I find myself cycling through the instances and it takes me a bit of time to identify which instance I want to in focus.

I often have many VS @Code instances open. I’ve been using this technique to differentiate them by titlebar color so I can see which one is which. I made it an extension – will publish it soon!Options1. Pick a custom color2. Pick a random color3. Pick a predefined color

About Last Night

I was working on 4 apps at once last night, along with several articles in I am crafting in markdown using VS Code. This motivated me to complete this project
After I had a working extension completed, I created a simple animated gif and shared it on twitter to see if anyone else was interested. Then I went to bed.
I woke up this morning to more positive reactions than from the community (thank you). I also received many great contributions already (thank you again!).
