Primary school use of iDoceo

As a Primary school teacher, I have used gradebook extensively for the past few years ... fantastic.

I am now using planner and wonder if you can be in class view and switch to planner with one touch? I have a 'Diary' button at the top of my view but not 'planner'.

There is no planner button on top but if you tap on the diary button you will see the planner as a tab.
Since iDoceo keeps track of your previously selected tab you'll then have to access to the planner with a single tap on 'Diary'
