• Basic support for a control is usually useable for the most common usecases.
• Mostly complete support should be include all but rarely used features.
• Complete support is support for everything that Clear Coat will support (which isn't always everything IUP does).

These I don't plan to implement, and I'm not sure I want in the library:

• Cbox (absolute positioning is bad, but if it was useful for a custom layout, I might implement it)
• BackgroundBox (backgrounds normally don't need changed)
• FlatButton (use a regular button that looks native)
• GetText (overlap with other dialogs, modal, and limited)
• ListDialog (modal and limited)
• MessageDlg (overlap with Alarm and non-customizable button text, which is usually worse UX)
• Sbox (I've never seen a program with one of these)
• Spin and SpinBox (text boxes support spin controls)

These I may implement, but at this time are lower priority:

• Plot
• Scintilla
• WebBrowser
