However, I still couldn't figure out how to make it work with a text node, where the each choice that is inserted is highlighted in select mode.

You mentioned storing the results of vim.fn.getreg('"') in a local variable and then applying :gsub on it (if I understood correctly), but I don't know how to do that.

So, the issue is that gsub returns 2 values, and these are unpacked into two arguments to t, which caused your first issue (t expects a table as the second argument)
What you can do to fix this is write something like local gsubbed_text = ...:gsub(...) and then pass gsubbed_text to t.

Oh, I see it now. I wasn't sure where to define that variable, but I changed my original snippet like this:

    c(1, {
      d(1, function()
          local gsubbed_text = vim.fn.getreg('"'):gsub("\n", "")
          return sn(1, fmt("{}", { i(1, gsubbed_text ) }))
        end, {}),
      d(2, function()
          local gsubbed_text = vim.fn.getreg('+'):gsub("\n", "")
          return sn(1, fmt("{}", { i(1, gsubbed_text ) }))
        end, {}),
    }),

It's working now. Thank you very much!

function ExitNode:jump_into(dir, no_move, dry_run)
	if not session.config.history then
		local next_node = util.ternary(dir == 1, self.next, self.prev)
		if dir == 1 and next_node then
			vim.print("")
			self:input_enter(no_move, dry_run)
			return next_node
		end

		-- If exiting node from the end
		if (dir == 1 and not self.next) then
			self:input_enter(no_move, dry_run)
			return nil
		elseif (dir == -1 and not self.prev) then
			self:input_enter(no_move, dry_run)
			return self
		end
	end
	return self
end

I've started by such a function, this is how you suggested, right?

I think this is what you told me, right? This function should return false when we're at $0 and it is root snippet

Almost, the new node is returned by safe_jump_current, we'd have to handle it's return-value
