From what I've read, the stack app was supposed to be discontinued but I'm seeing two different apps in Cydia, "stack" from the ste packaging source and "stack alpha fr" from the SOS Cydia source. I installed the first one and stacks sort of worked, it was place in the center of my fiveicondock and I could move it. It already had 2 apps in the stack which I was able to remove but not add and there was no stack settings. I uninstalled it and tried the french source one and there isn't anything, no settings no app. Can anyone shed some light on this?
