I would like to have more powerful tooltips 


- Prevent the opening of a tooltip via the show event and preventDefault (or similar)

- Prevent the closing of a tooltip via the close event and preventDefault (or similar)

- Have tooltips which can have their autoHide option determined by whatever they are hovering over, hence half the page could use 'hover' tooltips but more complex tooltips on the same page could use a close button. Could possibly accomplish this via the previous point

In general on this last point, you typically have a single tooltip widget on the page attached to the body, you may want more than one style

- Within the show event have access to the element on the page that the tooltip is above, (if there is already access I couldn't see it)

Do not hide the tooltip if false is returned from an options.hide function.

Use Case: I need to show tooltips on the chart and keep them open onSeriesClick.
This is so they will appear on the PDF when generated giving better readability to the PDF.
I see that by design autoHide=false still hides tooltips on mouse click - but at least let the developer have a pure control over hiding it via the hide method return.

The contentTemplate will be usable in MVVM bindings that points to an css id tag element in order to pull the Tooltip's contents.
