Question

I'm wondering if there is a way to make the way that a modified file show more obviously than a [+] at the end of the filename. I was thinking something along the lines of a ❌ icon and a checkmark ✅ if the file is saved. Would there be any tips on how to do this?

It is possible, yes. This requires writing custom section instead of using section_filename:

local my_filename = function()
  -- In terminal always use plain name
  if vim.bo.buftype == 'terminal' then return '%t' end
  local modified = vim.bo.modified and '❌' or '✅'
  return (MiniStatusline.is_truncated(140) and '%f' or '%F') .. modified .. '%r'
end

You can use it in combination with default active content like this:

local active_content = function()
  local mode, mode_hl = MiniStatusline.section_mode({ trunc_width = 120 })
  local git = MiniStatusline.section_git({ trunc_width = 40 })
  local diff = MiniStatusline.section_diff({ trunc_width = 75 })
  local diagnostics = MiniStatusline.section_diagnostics({ trunc_width = 75 })
  local lsp = MiniStatusline.section_lsp({ trunc_width = 75 })
  local filename = my_filename()
  local fileinfo = MiniStatusline.section_fileinfo({ trunc_width = 120 })
  local location = MiniStatusline.section_location({ trunc_width = 75 })
  local search = MiniStatusline.section_searchcount({ trunc_width = 75 })

  return MiniStatusline.combine_groups({
    { hl = mode_hl, strings = { mode } },
    { hl = 'MiniStatuslineDevinfo', strings = { git, diff, diagnostics, lsp } },
    '%<', -- Mark general truncate point
    { hl = 'MiniStatuslineFilename', strings = { filename } },
    '%=', -- End left alignment
    { hl = 'MiniStatuslineFileinfo', strings = { fileinfo } },
    { hl = mode_hl, strings = { search, location } },
  })
end
require('mini.statusline').setup({ content = { active = active_content } })

This works an absolute treat. Thanks so much for taking the time to help. I was really struggling to find/follow the documentation for how to identify if the buffer is modified.
