QOI – The “Quite OK Image Format” for fast, lossless image compression g github.com 200 JeanMo 4 years ago 103 comments
From my perspective its very confusing for beginners to switch to a proper IDE after using this. And I will not mind the argument that "proper" IDE are overwhelming. If you are new to programming most likely everything, including BlueJ, is overwhelming. And with a good teacher and a good introduction I don't think its too much for beginners to use something like IntelliJ.
Just use the "correct" tools right away.
//edit: The IDE might improved a lot since the last time I used it. Didn't wanted to talk bad on BlueJ itself.
