It is very easy for users to accumulate tabs when using GoodNotes, especially since they don't have to choose to close or keep them when closing the app. As time goes by, the buildup of tabs hinders the user experience. For example, when opening an older document whose tab was never closed, the user has to swipe through the endless sea of tabs to find the document they were working on moments ago. Additionally, closing tabs rapidly could be improved on because when the user closes a tab, the next tab has to animate under the user's finger before they can close it.

Features like having an option to automatically close tab after a period of time, tab search, tab overview (like Safari) and tab groups can improve this experience.
