Addition of option to make pattern invisible in Toolwiz applock

Components

Toolwiz App Lock(LockWiz) is a open source project from Toolwiz. It is an amazing way to protect your privacy and security on your Android phone. With LockWiz, you will never worry too much about the leakage of your personal sensitive date. Once you set lock for individual APPs and encrypt multimedia files – nobody will be able to access them without a correct master password - giving you entire control over who sees what.

Proposal

The main purpose of this app is to secure applications on my phone with a pattern that no one else knows besides me but this feature cannot be used to maximum capacity if an intruder can easily see and memorize my pattern while I unlock the application on my phone, I would like to suggest an option to make pattern invisible while unlocking app to increase security in the application.

Mockups / Examples

This is a screenshot of other applock applications I have reviewed,as you can see it has an option to make pattern/password invisible or invisible.

This is the toolwiz app without my suggested feature

This is what the app should look like if my suggestion is implemented.

Benefits

Invisible patterns make it more private and more secure to unlock app especially when in public or surrounded by people. I think this feature if implemented will go a long way in maximising the full potential of the toolwiz app lock app.
