Changelog:

Fixed a crash when watching/tracking a variable in a room with view enabled.
Heavily optimized texture swaps and vertex batches, spawning many trackers won't have much effects on the GPU now.
Added documentation in the README.md
Added more feedback so the user is always aware of what's going on.
Improved code structure
Added failsafe when executing a console script.
Custom commands can now rely on the argument_count instead of checking if an argument is empty.
Fixed console depth incorrectly set to 0.

Note:

If you want, you can download the source code to try the console for yourself before integrating it into your project.
