Sure, but I don't think it was available out of the box for Ubuntu until recently (I could be wrong), and I also think Windows 7 invented snap-to-sides (could be wrong on this too).

Linux has always been the OS where you can do just about anything you want with enough research and effort, but it still matters what the most mainstream distro offers out of the box at any given time.

I do believe that WM feature was available long before Windows 7... I recall similar options in many WMs as well as apps like Gimp, called sticky edges, edge attraction, snap-to-borders, and so forth. It seems like a fairly apparent idea to assist window placement, and i’d be surprised if it hasn’t been around in some form since the 80s.

Linux is highly extensible and modular, so it’s hard to say what it provides ‘out of the box’, even a given distro. For almost any distro, it’s very simple to start using a different WM (literally 3 steps).

I suppose it’s true that for the majority of users, what the defaults are is more important than an option merely being available as most people will never even read the settings menus.

My favorite feature, minimize to title bar, seems to be left for Window Maker and KDE, everyone else apparently has dropped it.

Xfce calls it shade window. I believe it is still there, and can be configured to be double click, or whatever you'd like.
