Thanks for the feedback! I’ve actually been talking about these things with the devs on GitHub.
If you don’t mind me asking, what’s your screen resolution? Are you using GDevelop with a tablet, with a laptop (with probably a physically smaller screen), or from a desktop computer (with most likely a physically decent sized screen)? I’m using GDevelop mostly on a desktop computer, with a 1920x1080 resolution.
This discussion started because some of the icons I made work well on bigger sizes, but when downscaled to 16 pixels, they become a bit too small. So for once, this isn’t something I personally prefer or recommend. It’s just something I’m testing out. If it doesn’t work and if there isn’t any reason to change the icon sizes, I’ll have to rethink a few icon designs, but that’s not a problem.
