I think new themes and features would be cool if Glitch adds 'em. I honestly suggest adding themes and features on Glitch editor. So, hopefully, they would implement on themes and add it. Also, they can add Community themes where there would be a Glitch Store where you can install themes and apply them to the Glitch editor. I find this a great feature as I believe the current themes are not enough and can be irritating due to their appearance. So, would love if they could add this feature.
