This program adds Win7 style window dragging and resizing to XP, Vista and Win7, with MANY additions and improvements. Drag windows to the screen edges to automatically resize them to fill half the screen. Drag to the top to maximize it. Dual-monitor systems are supported. Unlike Win7, both left and right edges of both monitors are usable. In addition, you can set custom split points for each monitor and drag windows to the top left or right corners to resize them to any percentage of the screen you want. Half screen splits are usually too narrow for a web browser, now you can resize them to more than half and use the remainder for other windows. AeroSnap Plus also adds menus to control many window attributes, including: transparency, roll-up, "Always On Top", forced resizing, and single window screenshots. The tray menu includes toggles for showing file extensions, showing hidden files, screensaver enable/disable, and AutoPlay enable/disable for CD/DVD/USB drives. The tray menu also lets you dim the monitors, power them off, blank the secondary monitor, or start the screen saver. Individual features can be disabled if they are not wanted or conflict with other utilities. Completely portable, no installation required.
