Lockdown pro has this option, it's 99 cents right now.
If they're apps you won't be using like stocks and voice memos then you won't have any problems using the feature.
It you're doing like me and hiding apps and creating activator menus, you'll run into a problem. Hidden apps do not show up in the multitasking switcher. They still multitask so that when you reopen them via the activator menu they're in the same state as they were when you left them, you just can't get back to them via the switcher.
Even with this limitation, lockdown pro is still well worth the 99 cents.
so i just purchased this app. gives an error on cydia when it tries to download.
What error? You can always write the developer to let him know/ask about it, he is very good at responding to emails.
I purchased it earlier this afternoon when it first came out in cydia without any issues and he already released an update for it today. I did the update without any issues as well.
I wonder if the error has anything to do with the increased traffic in cydia.
If you have twitter you can also ask him on there, on twitter he is iptmdeveloper.
Okay that I can't help you with, I'm sorry =/ I currently don't have any control center tweaks installed.
But like I said, best thing is to write the developer and let him know of any and all issues you may have. I have written him many times in the past, he is great at fixing and implementing things to make his tweak better.
i emailed him with some info, already got back to me and says he will have a fix soon. seems like a great dev.
