That's what I ended up doing. I do like the method for switching apps though. I have been using similar gestures on my iPad for quite a while.
As for multifl0w, I found that using tweaks like springtomize to enhance the stock appswitcher, there's really no need for it. Visually it looks better but is basically the same function. I try to save my resources where I can.
No and no. Just set it up to activate like normal multitasking with a double tap of the home button and you're good to go. Multifl0w is how Apple should have implemented multitasking. It truly is amazing and one of my few 'Must Have' Cydia apps.
Is there any app or tweak that interferes with zephyr? I installed it and it was working fine but now I can switch between apps but when I swipe from the bottom it shows the multitasking tray but if I let go it slides back down. Pressing the home button twice also does nothing now. Could it be springtomize 2? I installed that after zephyr
Edit: I can confirm that uninstalling sprintomize 2 fixed the issue and I can now use zephyr or double press home button. Does anyone know how I can have sprintomize but have it not interefere with zephyr?
