As a Roblox developer, it is currently too hard to utilize the icons of classes utilized in the explorer in areas outside of studio. What has been resorted to instead is to export information from StudioService::GetClassIcon via ReflectionMetadata, or simply manually create assets for each asset id both of which are rather tedious and must be updated manually.
If Roblox is able to address this issue, it would improve my development experience because it would allow me to much much more easily produce the icons used within studio in-game. This would be particularly useful for those who want to create a Roblox-like environment, such as for tutorials (e.g. Lua Learning style), or just in-game emulation of studio/plugins in general.
