This has been a thorn in my side for… going on 20 years now. On my Windows machines, I’ve always been able to resize my windows from any side, which is extremely handy for uncovering icons, organizing your desktop, and so on. Really just an indispensible and basic function I use every single day. Then I get on my Mac and… god damn it. You always have to go down to the corner to resize a window, which isn’t always the best option.
I don’t know if this was widely known before now, but I just found out that OS X 10.7 will let you resize windows by pulling on any edge. Huzzah! My decades-long nightmare has ended!
