Elixir Language Support
.ex and .exs files now get a dedicated purple EX icon in the file tree and full Monaco syntax highlighting for Elixir keywords, strings, and module names. Elixir projects are immediately recognizable without any configuration.

Why You Need This
How this feature boosts your daily productivity
Opening an Elixir project without language support means all .ex and .exs files render as plain text — no keyword colouring, no module name differentiation, no icon distinction in the file tree. With Elixir support added natively, Phoenix and mix projects read as clearly as JavaScript or Python ones.
How It Works
