Recently, I searched the possibly of opening several projects open a the same time. This would help my group in that depending on which project they happen to be working on. As I run my club at lunch times, I get children who may come and do a project and then come again at later date to try out another project.
As I cannot open several projects in Scratch 2, stand alone version, at the same time . Instead I decided to go to File Explorer and right click on each project and added these to my desktop. My pupils can then double click on the project they are interested in looking at depending on the stage they are at.
