Hi, sorry for the late reply! Yep, your feedback is totally right! However, the reason why I use Godot in the first place is because it is THAT easy to setup, and welp, making thing just works. In this case, because of the app is quite small, that's why I choose to use Godot to making this tool 😅
But other than that, yep, I will disable anti-aliasing for this one. I think it's also really true that it's quite blurry at the moment. So really thank you for trying this out and I really appreciate your feedbacks!!!
