Better method to enable/disable "locking"

Having to click the little lock icon to show the editing properties after completing a drawing is currently very tedious. Would request a better approach to this.

Suggestion 1 (more desirable):

- Double tapping (or repeatedly tapping) the same shortcut key could enable/disable this "locking" mechanism.

Suggestion 2 (less desirable):

- Create a dedicated shortcut key for enabling/disabling locking

As an aside: I think there should be a global toggle/setting for this locking mechanism. Some workflows might want to edit after every drawing, while others might want to just go with the flow and not be disturbed. Even more ideal would be to accommodate all of these on a global and per-tool level with the option to decide in preferences.

Maybe a settings box with the following (could be more concise/better worded):

- [Single Choice] Global Tool Locking Enabled; Global Tool Disabled; Per Tool Locking
- [Checkbox (Shown if Per Tool Locking Selected)] Remember Tool's Prior Locking Setting (otherwise use the default as set by the app)
