Provide a ability that can customize some toolbar-button(I read documentation, just support customize the entire toolbar, that not enough), and provide a hook 'whenEleCreate' for every toolbar-button.

I can initialize SimpleMDE like that(I want realize image upload when i click image button):

this.smde = new SimpleMDE({
  initialValue: this.content,
  element: element,
  spellChecker: false,
  toolbar: {
    image: {
      action: null,
      className: 'md-upload-img fa fa-picture-o',
      whenEleCreate: function (el) {
        let self = this
        // add custom class
        el.classList.add('md-upload-img')
        // append input element
        let inputEle = document.createElement('input')
        inputEle.setAttribute('type', 'file')
        inputEle.setAttribute('multiple', true)
        inputEle.setAttribute('accept', 'image/*')
        el.appendChild(inputEle)

        inputEle.onchange = (evt) => {
          let imgs = evt.currentTarget.files
          if (imgs.length) {
            let xhr = new window.XMLHttpRequest()
            let formData = new window.FormData()
            for (let i = 0; i < imgs.length; i++) {
              formData.append('upload_img_' + i, imgs[i])
            }
            xhr.open('POST', 'http://localhost:3000/upload', true)
            xhr.onload = (event) => {
              if (xhr.status === 200) {
                let cm = self.codemirror
                let stat = self.getState()
                let options = self.options
                let res = JSON.parse(event.target.response)
                let urls = res.urls

                urls.forEach((url) => {
                  self.replaceSelection(cm, stat.iamge, options.insertTexts.image, url)
                })
              } else {
                console.log('fail')
              }
            }
            xhr.send(formData)
          }
        }

        return el
      }
    }
  }
})

This needs to be a built-in option for SME. Any chance we'll see this incorporated into SME soon?
