It will be like a "Export session", because some functions load external resources from original path file and not a copy, but it will be done
PDF file takes too much time to open because each page is converted to png file (Godot Engine, where Expanote is made, is not compatible to open a pdf file out-of-the-box), tho I will try to convert it to a lower quality so conversion will be fast, but it can currently be used for pdf with few pages
I will try to add those functions for Draw window, but currently the priorities are other functions for the program itself, so it will be added progressively
Edit: Thx for your feedback!
