Thanks for this @CaeChao! Just a few comments

Should just default to the basics:

Suggested change

	local checkboxes = opts and opts or { " ", "~", ">", "x" }
	local checkboxes = opts or { " ", "x" }

I think sorting here based on order would be more robust. Something like:

Suggested change

	for k, v in pairs(client.opts.ui.checkboxes) do
	local order = v.order
	if order and type(order) == "number" then
	-- sort the checkboxes based on order
	checkboxes[order] = k
	end
	end
	table.sort(checkboxes, function(a, b)
	return client.opts.ui.checkboxes[a].order < client.opts.ui.checkboxes[b].order
	end)

Thanks for the advice! I'll commit the changes

Not sure if we want to add something like this, but accessing the tags via the "smart action" is quite handy IMO:

  -- show tags if possible
  local current_wrod = vim.fn.expand("<cWORD>")
  if current_wrod:match("^#") then
    vim.cmd("ObsidianTags")
    return
  end

@CaeChao thanks for bringing this feature over the finish line.
