I would also love to see functions implemented. I know you can just do a fast loop or use event groups and turn them on/off, But purposely built Function groups would be great to have. E.g. you could just use the event group functionality that already exists, but add the ability to execute a group which would immediately set the event group the next statement to run.
Also the ability to access an object by its name. An example for this would be I've made a tide prediction app for android, it consists of approx 40 counter objects. Because counters don't have alterable values, i can't simply loop through and select a counter and make changes. I have to repeat code and manually manipulate each counter.
I think this thread is a great platform to make Fusion 3 perfect. Sub events, ability to reuse code and objects globally easier, increased ease of use when dealing with object instances and functions are the main things i hope to see in Fusion 3.
EDIT: just saw this post by Snail: Please login to see this link.
Much better explanation of functions and how Fusion would benefit
