MaxMax is an easy-to-use tool that prevents maximised windows from fully covering the screen, which means you're able to leave a margin on the left, right, top or bottom.
This can be useful if, say, you want to monitor some desktop gadget or similar tools, but find they keep getting covered whenever you maximise a window. You could always minimise it again, of course, or perhaps press Alt+Tab to switch tasks, but with MaxMax running this doesn't have to be a concern at all.
By default the program leaves a 160-pixel margin on the right-hand side of the screen. If that's not suitable for you, though, right-click the icon, select Configure, and tweak the settings to suit your needs.
In our experience this all worked very well, but if you have problems with particular applications then that also doesn't have to be a major issue. By pressing a user-definable hotkey (left shift by default) you're able to disable the program temporarily, and so fully maximise whatever other apps you might happen to be using. And MaxMax also provides an Exclusions list where you can name any processes you'd like it to ignore; these will be allowed to maximise as normal.
