Pixel art resolution setup

Hi folks! I’ve been making my prototype and ejoying the engine a lot, but a have a few questions regarding pixel art setup in Defold.

My current approach is to set the engine display resolution at 640x360, resize to 1280x720 with defos, and use ortographic zoom at 2. This works, but I think the GUI has some issues like the fonts not rendering well on small sizes, it is like the bitmap fonts lose detail. Another way I thought, is to set a high display resolution like 1920x1080 and scaling up game objects by 3 and setting zoom to 1. I want a setup that is easy for me to see in the editor where the GUI elements are in relation to the game elements, so it is easier to position GUI elements. What would be the optimal solution for this? How do you setup your projects for pixel art games?

Thanks
