Tiny Pitaschio doesn't even use an installer; you just start the program and get going. Oh, and there are some many ways you can go with Pitaschio. You can snap windows to a grid. You can disable troublesome keys like Caps Lock, Insert, and the Windows key. You can disable minimize, maximize, and close buttons. Those are just a few of the options on the main screen. From the buttons on that screen, you can reach useful tools like Autoraise, which pulls any window you mouse over to the top.
Perhaps the most useful tweaks are the mouse shortcuts, mouse button and wheel combos that do different things according to where the cursor lies and what you've set them to do. For instance: At default, double-clicking the desktop brings up the screen saver, and wheel-clicking a title bar minimizes a window. Each combo offers a variety of selectable options, from turning off the monitor to opening the Control Panel to changing virtual desktops.
Pretty much the only thing that gets me about this program is its name, which I keep confusing with Pistachio--but never mind. Pitaschio is as cool as ice cream.
