Well ...  There are (IMHO) two rather different uses of zooming.

The first is simply to achieve a desired amount of magnification,
in which case features such as Ctrl + / Ctrl -, or a drop-down
with pre-defined magnifications, will usually suffice.

The second occurs when there is one specific region of interest that
one wants to examine in considerable detail (e.g., the kerning between
an anomalous pair of characters, or the exact shape of an apostrophe/
quote/prime/w-h-y.).  In this scenario, the magnifying glass is
appropriate but poor, in that (a) one has to hold the button down,
and (b) the zoom is fixed.  A superior alternative is the marquee
zoom : one draws a rectangle around the region of interest, releases
the mouse button, and the desired region fills the screen.  In all
programs that provide the latter, I make enormous use of it (and
never use a virtual magnifying glass, if offered); so I really miss
its functionality in TeXworks, and regularly bemoan its absence.
