cftool functionality missing in recent matlab version?

In 2010 version cftool used to contain buttons for various task such as post-processing, this gui way is missing from recent release, I know it can be implemented by writing script but gui is much better. why are those things missing?

How can i get this Fiting, exclude, ploting and specially analysis in recent version. We were able to plot derivative and other postprocessing analysis in older version.
