-### Creating Custom Skins
-
-1. Create a folder like this (recommended name: 'src/skin-custom-...')
-2. For a start copy files from one of the existing skin folders (src/skin-...) 
-   to the custom folder:
-   - ui.fancytree.less  (required)
-   - icons.gif (if needed)
-   - loading.gif (if needed)
-3. cd to your fancytree folder and run `grunt dev` from the connsole.<br>
-   Note: NPM and Grunt are required. 
-   Read [how to install the toolset](https://github.com/mar10/fancytree/wiki/HowtoContribute#install-the-source-code-and-tools-for-debugging-and-contributing).
-4. Edit and save your ui.fancytree.less file.<br>
-   The `ui.fancytree.css` will be generated and updated automatically from 
-   the LESS file.

-
-  - In strict mode, how can a user leave an embedded text input, if it is
-	the only control in a row?
-
-  - If rows are hidden I suggest aria-hidden="true" on them (may be optional)
-	=> aria-hidden currently not set (instead: style="display: none") needs to
-	be added to ext-table
-
-  - enable treeOpts.aria by default
-	=> requires some benchmarks, confirm it does not affect performance too much
-
-  - make ext-ariagrid part of ext-table (enable behavior with treeOpts.aria option)
-	=> Requires stable specification
