Custom nightwatch command waitForElementClickable() - tested with nightwatch 1.1.13 - inspired by https://gist.github.com/JamesBoon/dc19bc202673e19baf4b9b85d78df27f

waitForElementClickable.js

// Much simpler version (this history for the previous ones), suggested by @beatfactor
// More info https://github.com/nightwatchjs/nightwatch/issues/705

module.exports.command = function(selector, timeout=5000) {
    this.expect.element(selector).enabled.before(timeout);
    this.perform(() => {
        // eslint-disable-next-line no-console
        console.log(`🖱️ Element clickable: <${selector}>`);
    });
    return this;
};

FYI: broken by nightwatch 1.1
New gist version: now working with 1.1.11

use nightwatch's logger

const { Logger, symbols } = require('nightwatch/lib/utils');
const { colors } = Logger

module.exports.command = function (selector, timeout=5000) {
  const start = Date.now()
  this.expect.element(selector).enabled.before(timeout)
  this.perform(() => {
    const message = `Element <${selector}> was present after ${Date.now() - start} milliseconds.`
    Logger.logDetailedMessage(`  ${colors.green(symbols.ok)} ${message}`);
  });
  return this
};

It may be better to use this.globals.waitForConditionTimeout for the default timeout.
