Currently, if a user needs to export to a file or select a folder they have to do it for every session. A session being the length a document is opened.
If they close XD, close the document or reload plugins they have to reselect the file reference.
Betrand is writing a plugin to export vector graphics for his game, Vectobots. His game sits on one side of the screen and XD on the other.
Working with a lot of graphics he has numerous document windows open. In each one, he selects the file or folder to export to. Then he uses plugin panel to export on update events. He often has 20 designs open at a time and has to reselect the folder.
With the new persistent files feature, he has only had to choose the folder once and he hasn’t been prompted again.
