So after bulding up an apps collection of over 150 apps and seeing my applications menu grow to a huge list, i have thought about how this could be solved.
Imagine, being able to move applications into a sub-menu. This item appears on your app list as an item, you then swipe left on it and a third page comes over full of the apps you have put into that sub-menu.
If you like this, please support it by voting on the Microsoft feedback page below:
Enable application sub-menu – Swipe left on menu item to bring third page.
