Changing notes' sizes and positions is permitted but everytime a note is closed an reopened the size and position is the default (upper left corner). I understand why is always opened at that position (but i would prefer to set up that position by myself) but i really don't understand why i'm allowed to change the size of a note , to, for example, write more content and read it properly, and then when i close and reopen the note the size has changed to the default one. And im talking about a case when the pdf isn't closed and reopened. Take into account that pdfs are not just books, a common use is for reading educational slides and usually you have a fair amount of free space where you can put your big notes on.
