You're kind of tired of always clicking the same button every time you start an app
You've made a Netflix app for you Mac, and you want it to always start in the Horror section
You want your Gmail mac app to always start in the Sent emailsview (if you do, please tell us why)
How to do it
Open the app you want to change
Navigate to the view you want it to start on from now on
Open Preferences and tick Always launch on this page
What it looks like
Here's an example where we're telling the Netflix app to always start in the Horror section. Note that we didn't have to type anything, we just navigated to the horror section, opened Preferences and ticked the launch box.
Good to know
You can always disable the start page by removing that tick mark.
