Code Issues Releases Wiki Activity

Load Database task async wait moved to LoadDb runnable rather than blocking UI thread (in case the file is very slow, or the user is very quick to enter their password)

Browse Source 
Database Unlocked warning notification now uses a 4.1 extended "Lock Database" button, and the main action is now just to activate the app.

PasswordActivity no longer loads the database file into memory ready for loading if it's already loaded and we're showing QuickUnlock instead.
