Yes some app's have " save at closer",( save position & size"),
Some app's just save size & some just have a default size...
Anyway..( Most of all the one's i have tested, will save size at closer, but not position( default back to center of screen ) yes some saved both, ...
This has to be changed within the Source code of some app's, Or manipulated via an app like @Luca_Pavan mentioned,
For app's that you reopen like,( files/folders/Software-mgr/ect) That save's size not position..
It maybe an Idea to suggest this for in new Zorin 17..
maybe via contacting at bottom of of link.
