We long had an extension for the Visual Studio IDE, the Lombiq Orchard Visual Studio Extension. One of its features is that a button on the Visual Studio editor’s toolbar can light up when a new error is logged by the application one is working on. And now BlinkStick LEDs can light up too!
Check out a demo of the feature here. The integration is pretty simple but basically, when an error is logged you can make a BlinkStick device blink or light up continuously with a configured color.
What do you think? 
The extension is open-source BTW and the part with BlinkStick is in the BlinkStickManager.cs file on GitHub (I’d link to it but as a new user I can only include two links, so well… You can get to the GitHub project page from the above linked Visual Studio Marketplace page).
