Reaching back a bit to the zooming discussion. LV doesn't have zoom, but it is because it wasn't designed in and is difficult to retrofit. Sure it could be done, but there was and still is some concern that some will choose to use zoom as a substitute for subVIs (modular programming). I predict it will appear in a future version, and will be similar to CAD tools or other engineering drawing tools.
If you know what to search for, you can actually find an early access version of a LV variant with zoom, vector graphics and the like.
