Extended Sequence Scripts for GMS 2.3

What can this collection of scripts do?

• Manipulate Tracks and Instances in a sequence while the sequence is playing
• Change properties for entire Groups of Tracks
• Add readable variables into the Sequence Tracks
• Readable variables allow support for things such as Text Elements

I don't know if this will be of any use for anyone, but I thought I'd put it out here :)

INSTRUCTION
You really only need the scripts from the downloadable project file, but the project includes some examples of usage.
