rectangle is a better and free and open source alternative to magnet, also auto hiding the toolbar in safari helps out a lot when using one single website, say writing a doc, or coding on a server, and similarly, when in fulscreen mode, if you open multiple windows on safari, then u can browse between them easily with swipe gestures rather than moving the cursor to the top and then selecting the website, the caveat is u need to know the arrangement of the webpage, but if it is one or two, then it works fine.
Hmm never heard of rectangle, I'll look into it though! I was looking for an open source alternative at first but didn't really find anything. Thanks for the tip!
