WLock - an addon for Blender 2.8 which allows to lock 3D view rotation using hotkey (default Alt+W).
Maybe you need PRO version?
Our team CGjazziQ is glad to present a very helpful addon for Blender 2.8
This addon allows to lock 3D view rotation (only 3D view) using hotkey. As an additional indicator a 'lock' icon is displayed (can be set up or disabled in Preferences).
You can have any number of 3D views and each one can be locked/unlocked independently.
One of possible usage - for 2D animation. When you work with orthogonal projection you can by chance rotate your viewport. This can be very annoying. And now you can save yorself from this with a simple hotkey.
Another example - use it for sculpting.
One powerful feature is opportunity to lock 3D viewport not only from orthogonal view, but for any view from user "camera".
Just use the addon hotkey combination a couple of times. We are sure you will find many situations when this addon will help you to work more comfortably.
