All plugin developer can update there plugins to work like that since FM15 if I remember correctly. Troi are updating all there plugins for FM16
While a plugin can offer those, they all keep the existing functions.
And if you need to be compatible to FileMaker 15, you may better keep using the old way.
Compatibility isn't a concern with me although with other devs it will be.
What concerns me is plugins that drift away from the ease of use concept and require the use of many steps to reach a goal. I don't mind the existence of those steps but if they were packaged in a script step in the FileMaker Way and offered a dialog requesting input for the several values like the email dialog that asks for to, subject, attachment, etc. or the web viewer that has input fields for address city state, etc.
The dialog might have checkboxes or radio buttons for the options rather than requiring the complexity of the current methods.
Yes, I learned to hate text coding starting with DOS command lines, basic, xBase, etc. I forsake them all for the ease and reliability of FileMaker's point and shoot methods and find that FileMaker is incorporating various elements that return me to the nightmares of debugging lots of text lines with no help...
