As a Roblox Developer it is currently too hard to personalize my studio experience due to the inability to customize Roblox Studio Themes.
There are some really nice looking script editor themes out there like Spacey and with this limitation of not being able to customize our Roblox Studio Themes to fit with our script editors is annoying and the rest of studio look weird.
If this was addressed, it would improve my development experience because I would be able to make Roblox Studio the way I want and the current themes that we have are too limited and lack customizability.
