This forum's really for stuff you want to pay someone to do. Was that your intention?
Icons are potentially a bit tricky - maybe someone knows better, but the Web App doesn't necessarily know what OS it's installing to since it's totally multiplatform - so it might be hard to come up with an OS-specific icon.
So I downloaded the Espruino IDE web app on my Mac, but it looks out of place with the other Big Sur icons. Can somebody make a Big Sur icon for the Espruino Web IDE? Nothing too complicated, just the logo on a colored/gradient background is fine. Not sure if this is the place, so please tell me if this is where I should be posting this. Thanks!
