What I do in the meantime is just reopen the same file again while it's open in paintstorm and it refreshes to the last saved version.

Autoupdate will require the software to be reading from disk any modification which i think will slow down with big canvases, however I can see that a shortcut like F12 in photoshop (Revert to saved) which actually refreshes to the last saved version would be the best choice in Paintstorm

It's a usefull function, but it can be hard for programming, becouse it's conneced to other software library. We need to research this process before we can primise to add this function.
