[Request] QTree enhancement

[hawkeye64]

@rstoenescu
First of all, thank you for such great quality in a product. World class!
I started using QTree in an Electron product and it's very similar to a file explorer structure. Directories on the left and child contents of the selected directory on the right. Above the QTree is a number of shortcuts (Home, Documents, Downloads, etc -- directories).
What I wanted is that if a user selects one of these shortcuts, or a folder on the right, that the QTree is able to open and select the proper node.
I am doing this using an "undocumented" function,setExpanded, in the QTree. This occurs after I collect the children information of that folder.

    selectFolder: function (absolutePath) {
      // get parts for the path
      let parts = absolutePath.split('/')
      let path = ''
      let lastNodeKey

      // iterate through the path parts.
      // This code will get the node. If the node is not found,
      // it forces lazy-get by programmatically expanding
      // the parent node.
      for (let index = 1; index < parts.length; ++index) {
        path += '/' + parts[index]
        if (index > 0) {
          if ('folders' in this.$refs) {
            const key = this.$refs.folders.getNodeByKey(path)
            if (key) {
              lastNodeKey = key
            }
            else {
              if (lastNodeKey && lastNodeKey.children.length === 0) {
                this.$refs.folders.setExpanded(lastNodeKey.nodeKey, true)
              }
            }
          }
        }
      }
      this.selected = path
    },

This works pretty good, but I am concerned about it being undocumented. Is there a possibility this can be added in the documentation for QTree Methods?

Now, the enhancement part...
If a user has a large amount of folders (or expanded folders), when a folder is programmatically expanded and the the expanded key is not visible, that there would be an option to call <element>.scrollIntoView?
Thanks.
