Hi Paul,
For your question regarding the custom widget, that likely was made on a much older release of Tulip and is no longer compatible with the current releases. I can check with Pete and see if he has that customer widget still on hand and can re-export (no promises there though!)
As for the schedule & shifts tool - this thread (Shift and Schedules enhancements) has the most up to date information on what the Tulip team is considering for that feature, but as of now there are not prioritized enhancements coming for it.
