Todo & Ideas

• Adapt to WPF and UWP
• Support events (such as OnEnter, OnLeave...)
• Apply selectors by order - by type -> by class -> by name;
• With hooking - make sure to handle controls that were created after the form has been shown.
• Tool for editing the theme file
• Setting images
• Set the cursor icon
• Convertor tool to CSS

Any contribution is welcome!
