Currently, it is possible to add markings from the visualization Properties -> Data window. One could expect to be able to complete more operations on the markings from this window.
I think about having a button below New... which opens the Document properties -> Markings window / tab, or be able to complete all the available operations on the marking from a right-click.
I think this would make more attractive for some people (especially the ones getting known with Spotfire) to set adapted marking names if all would be "there", and make others more efficient.
Thank you for your consideration.
Kind regards,
Xavier
