Feedback appreciated.rtk.Slider's API has been promoted to stable (however vertical orientiation is not yet implemented)auto for rtk.Viewport.vscrollbar that will reserve space for the scrollbar if scrolling is required to see all contentrtk.Window now supports relative values (i.e. between 0 and 1.0 inclusive) for minw, minh, maxw, and maxh attributesrtk.Widget.hotzone attribute, which allows adjusting the area around the widget's normal boundary where mouse interactions will register. This can be useful to allow a widget to be clickable even if the user inadvertently clicks within the margin or spacing in a box, for example, which in particular can improve UX on touch screensonkeypress events when any descendant of the container is focusedrtk.Viewport.vscrollbar is set to hover (default) the scrollbar now becomes visible when the mouse enters anywhere within the viewport, rather than only when near the scrollbar gutterrtk.Window autosizing (i.e. when width or height is not set) when the window contains "greedy" widgets that want to fill their parent containers as much as possiblertk.Window:open() now defaults to center alignmentrtk.Widget.onclick, rtk.Widget.ondoubleclick, and rtk.Widget.onlongpress no longer require rtk.Widget.autofocus to be explicitly set or have a custom rtk.Widget.onmousedown handler to fire.
