No. LabVIEW will have four viewing sizes and will automatically switch between them every quarter hour, which we feel should give you time to focus on the broad overview (on the hour), the major architecture components (15 minutes past), the individual functions (half past) and the algorithm details (15 minutes before) in good rotation in order to keep your overall application fresh in your mind. The front panel will scale inversely, so that both panel and diagram will be at the same scale at half past the hour.
In all honesty... we are years away from even thinking about UI gestures for this. Keyboards may be obsolete by the time it is done. Years. No, I'm not joking, exaggerating, making stuff up or trying to set false expectations.
