I wanted to created a pull request with some improvements but could not as I'm not a collaborator.
One of them is to include a a bytecode inspector, as the new EOF format is on mainnet, yet EVM Codes UI doesn’t visualise its section layout.
Having a hex‑viewer style breakdown would aid comprehension and error detection.
I'm not an expert of a specific frontend framework but you may parse header/sections with ethereumjs-evm package (already supports EOF), and render each code section with a different colour
