Picture-in-picture : OnScreen

Say goodbye to the endless shuffling between tabs, windows, applications or spaces. 
With OnScreen, you can effortlessly capture any portion of your screen and transform it into a floating window that stays atop other applications. 
Whether it's a snippet of code, a shopping list, or a design inspiration, OnScreen ensures the information you need is always within sight, never obstructing your workflow.
Additionally you can create, view, and interact with notes that hover above your all other windows and move across multiple spaces.
