Task Till Dawn 1.9 brings full retina support to the Mac. I replaced all icons with high-resolution images and removed MacWidgets and QuAqua. Unfortunately this also means that dialogs within the application are no longer displayed as sheets. But I think this is no major loss. HiDPI display modes on Windows are now also supported, with better readable texts and icons with higher resolution.
Additionally there are a lot of small improvements to the user interface, which simplify the task administration. Tasks can be duplicated and enabled or disabled using the contextual menu.
It is also possible to pause the task manager, in case the execution of tasks should be suspended for a certain time.
