Thanks for your feedback.
1. Sorry, no we don’t yet support the recursive encryption of folders, due to problems caused when some users do not understand how this works. We’ll be adding an options page where advanced options like this will be possible to configure.
2. There’s no hotkey, but you can sign out quickly from the tray. You can also sign out by right-clicking anywhere almost in Windows Explorer and selecting AxCrypt | Sign Out.
3. Here we have a problem… We do not advocate this practice. Please read http://www.axcrypt.net/blog/use-of-different-passwords/ for a longer discussion about this.
