Thanks for telling me, now I see how to swipe apps away.
On my Oneplus One phone running cm 12.0, long-pressing the menu key ("hamburger" icon) shows running apps.
They can be swept from there.

You're right.  Even after swiping all those screens away, going into settings->apps shows lots of apps running.

On a separate note, it's funny that even when I have Mycelium open, it doesn't appear in the list of running apps.

Is there a mycelium rep here?  I need to reset my password on my mycelium.com account (+10% pre-registration), and the support@mycelium.com seems unresponsive

Hi. We get and read through the support, but we need the backend devs to actually do something. Sometimes we are waiting for them to get back to us on an answer too. There is a password reset option already.

I think I might have found a small bug in the latest version of Mycellium, but I figured I'd run it by the forums first to see if others have had similar experiences.

Last weekend, I created a new Mycellium HD account and decided I wanted to create a backup of it right after creation. When I tried to do so, I was told that I needed a PIN on the account before I could back it up. Fair enough, I set a PIN and continued to try and back it up. However, when I tried to back it up after setting a PIN, I received a message stating that the PIN was recently changed and I'd need to wait two days (288 blocks) before I could back up the account.

Has anybody run into this before? It was a little frustrating to not be able to make a backup of my new account, and it might be worth looking into for future releases.

I'm sure I have a backup of the seed, but I'm not sure if I have a backup of the account made through Mycelium. Before last weekend I hadn't used that wallet in about a year or so. Anyway, I thought it was a little odd that I wasn't able to backup the account after setting an initial PIN.

Any exchange to trade this coin?

You don't need to create an additional backup - your 12 word seed backup is good for all addresses in all HD accounts you create in mycelium, even for future ones.

If the checks and waiting times weren't in place, I could pick up your phone and make a backup without you noticing. I could set a pin, if I wasn't forced to wait then I could back it up then remove the pin again. You wouldn't know I have a backup and I could at any point decide to steal all your funds.
So while it might seem odd, it's necessary to protect you. And as mentioned, you don't need to back up again - you would just get the same 12 words shown again anyway.
