Add the Decoration widget

It doesn't do anything, but I've found it useful for filling up space with something mildly less boring than whitespace.
Include Tickit::Widget::Table::Paged

It's like Tickit::Widget::Table, but works better with more data, and renders directly instead of attempting to build on vbox/hbox.
Include Tickit::Widget::Layout::Relative

This one does layout based on positioning info, similar in concept to Android's RelativeLayout container.
