Curve fitting toolbox GUI change in Matlab 2016 compared to 2009 version

I have been using matlab for a long time and i had my 2009 version. in that the cftool command gave the curve fitting toolbox where i could easily smoothen the data before fitting using moving average. after fitting, i could easily analyse the data. for instance calculate differentials and integrals. it was easy to exclude data also. but in 2016 version, which i install today, the GUI is completely changed and i cannot find anyway to do those tasks. please help
