Something I find awkward with Krux is passphrase entry containing symbols, numbers etc.
As I loop through the different types of keyboard (lower-case, upper-case etc), the ABC button moves when it gets to the numeric keyboard (because it only has 4 columns rather than the 5 of the others). It means I hit the delete key by accident, meaning I have to loop through even more :-)
Any chance we could change the numeric keyboard to 5 columns? I'm happy to do the work if so.
