You guys are the best! Will there be a specification?

Importing private keys in text form, what vulnerability exactly does use of the clipboard introduce?

Soon
New version is just being made available to beta testers, in case everything is fine it will get out after we received enough positive feedback

I have to generate the private key of a brain wallet and import it into mycelium on the same device, which means I don't have a way to scan the qr code.  You're telling me not to use the clipboard,
and mycelium offers no way to type in a private key.

I'm on the road, so I can't fire up a PC and generate a qr code of one of my brainwallets.  I have an android tablet and a flip phone.

Scenario:
I have the bitaddress.org code saved; after turning off data and wifi I locate the file using ES File Explorer and open it in Chrome.  The bitaddress.org code generates a key.   Now I need to import the key to mycelium.

I have considered taking a photo of the qr code with my flip phone, then scanning the flip phone's screen (tested this and it actually works).  

Looking for further ideas, like some way to get the private key into mycelium without copying it to clipboard.  Out-of-the-box ideas that I haven't thought of.

How does one get to be a beta tester? i can volunteer if you want. Just to show my love for this app.

Import of private key from clipboard is disabled. You can only import through a QR code, but as far as I know, there is no safe way to generate a QR private key without using some web interface.

In general, it would be worthwhile to have the ability to work in text.

As a special illustrating case, and if you read my post attentively, the device generating the key to the brainwallet may be the same device running mycelium.  In this case it's impossible to use a qr code.
Or there might be people who still use mobile devices without a camera.

One can generate a private key on his tablet and copy it to clipboard, but this entails prohibitive risk, so for all practical purposes mycelium now can only import a key in the form of a qr code (from a second device or from a paper wallet).

The devs are busy working on the upcoming HD implementation, and I wouldn't want to distract them from that.  But just to move the conversation along, here's a possible scheme:   generate the private key, encrypt it with gpg, import it to mycelium through the clipboard, and decrypt it in mycelium.  I'm not suggesting the devs should devote resources to implementing symmetrical encryption for text private keys, I just want to bring attention to the issue of importing text.

Maybe there's a simple and secure way of importing text which wouldn't be too hard to implement.  Surely there's no harm in considering it.

Minor bug report:

In "Settings" the explanations are cut off after 4 lines of text. (look at "Expert mode" and "Aggregated View" for example)
