User configurable default view on app startup

Right now the left most navigation tab (first on the left) is the default view when app opens. For example, habits navigation tab is the first tab on the far left at the bottom so when Griply app starts it shows habits view (page). Instead let user configure the default view (page) to open when app starts irrespective of the navigation tab order. In my case, Icd like to see to do (tasks) view (page) when app starts and I want to specify it in the settings so that every time app starts it automatically shows to do (tasks) page.
