Seems, I've answered my own question... my "wish" that Qlik implement the native ability to scroll past the screen height, is finally implemented in June 2018 version...
upon further investigation I'd like to let people know..there may be forks of the screen resizer that actually work.
==>a fork of qlik sense resizer patched to work on QS3.2SR4
QlikSense june 2018 version has an "extend sheet" feature.
Native functionality for extend sheet and ability to scroll and see more stuff , without stretching stuff on the screen is a great feature!
Unfortunately, I believe my organization follows roughly a version (latest-1). Well the good news on that is it seems QlikSense releases an update very 2 months recently, and prior to that every 3 months, so won't be too long.
