This has been fixed in the latest pd-l2ork git as well as nested arrays 
now have properly aligned selection hotspot/selection box (latter may 
require further testing for regressions). For more info on the bugfix 
(it's a bit messy as I had to spend some time learning how this part of 
the code works) see:


Regarding sluggish scalars/structs, pd-l2ork already accelerates their 
displacement when editing and moving entire scalars around. I am still 
working on figuring out how to deal with struct selection and 
displacement at runtime.

>> * flickering animation with arrays and/or lots of scalars on screen
This is most likely due to scalars currently redrawing themselves every 
time you move something which becomes increasingly obvious when you have 
lots of stuff on screen.
>> * crashes with nested arrays when changing struct args
I've been experimenting with the patch provided in the bug report that 
has nested structs and no matter what I delete/change, I've not yet 
managed to crash pd-l2ork. If you find a way to do this, an example 
patch will be most appreciated.


P.S. Next pd-l2ork release is imminent with some really cool new 
features, like intelligent multi-connect and more accelerated operations 
(pddplink), as well as the usual bagful of bugfixes.
