AquaSnap – Flexible, Customizable Image Snapping
AeroSnap does not allow you to drag windows into the corner or to the bottom of your screen, but AquaSnap does. It will also display an icon when you’re about to snap a window and even supports multiple monitors. So, if you want to want to split your screen via AeroSnap, AquaSnap will make it possible.
Recommended: By default, AquaSnap will maximize a window that is dragged to the top to fit half of your screen. You can customize this behaviour.
AquaShake – Keep windows always on top
AquaShake is another built-in feature of the tool. It works similar to AeroShake, but will always keep the windows on top of all other windows, instead of minimizing all windows. Shake the window again to undo the effect. Additionally, it allows you to customize the shake detection sensitivity.
Recommended: It is recommended to change the default opacity, or you will not see much when the window is always on top.
AquaGlass – Make window transparent whenever you move it
AquaGlass, the third feature makes windows transparent when you’re moving them, so that you can see what’s behind them. Handy!
