Disabling sensor(s) in the panel when you want to leave windows and doors open has two disadvantages:
1) It's a pain in the neck, and
2) Then there's no security whatsoever at that location.
For some windows and doors, there's an easier and still-secure way to solve the problem. On our casement windows, I simply cemented another magnet in a position so as to close the sensor when the window is opened to the "open-but-monitored" position. Needless to say, the window is opened far enough to let in a breeze, but not far enough to let in a burglar. Our windows have flimsy plastic stops to define this position, so it's pretty easy to find the right spot, but lacking this, you could mark the windows in some way to define the spot. This also allows the lower sash to be opened upward, or the upper sash to be opened downward, or both -- the only criterion is that the sensor must align with the magnet to make the sensor report that the window is closed. If the burglar moves either sash at all, the alarm trips.
Doors are obviously trickier. I haven't figured out a secure way to do the same trick with a conventional door-like door, but for sliding patio doors, just think of them as horizontal casement windows and the same method works. We can leave the patio door open just enough to let the cat in and out, but not enough to allow a burglar to do the same.
True, a burglar might be tempted by the open door or window, but if they're in an instant-alarm group, he or she will be immediately scared off, and if your home is really attractive, you might avoid a broken window anyway.
