What are you missing from the TUI? The latest version has improved it a bit, it's more responsive now and you can navigate around the UI with the keyboard more easily (tab, up/down arrows, and pgup/pgdown). If you don't like it though, you can also use `--format text` for a UI-less experience that just prints things to stdout.

As for converting failures into forge tests, there's multiple tools offering a solution to that problem; check out (in no particular order):

  * the Recon VSCode extension (https://github.com/Recon-Fuzz/recon-extension)
  * fuzz-utils (https://github.com/crytic/fuzz-utils)
  * runes (https://github.com/Enigma-Dark/runes)
  * fuzz_parser (https://github.com/Enigma-Dark/fuzz-trace-parser)

Some of them use the Echidna trace output, while others (like runes and fuzz-utils) take advantage of the fact that Echidna saves these sequences as part of the corpus during runtime (particularly, in the `reproducers` and `reproducers-unshrunk` corpus subdirectories)
