Enhanced diagnostics UI for Neovim. 🚧 Highly WIP. Publicly available to make it easier for me to clone. Aims to gracefully support multiple diagnostics sources (e.g. multiple LSP servers).

vim.diagnostic.config {
    warden = {
        line_highlight = true,
    },
}

As opposed to the builtin virtual_text handler, this will also merge diagnostics from multiple sources and display the most severe one (the virtual_text handler only displays whichever diagnostic was received last). This will also include an indicator symbol showing how many more diagnostics (and their severity) that have been truncated on a given line.
