My feature request is for enumerated types.
Firstly, I'm really enjoying using Construct 2. It has a great design and is fun.
For non-trivial programs, the event sheet gets pretty confusing. From what I've seen, the standard approach for implementing a workflow is to disable/enable groups of events.
My preference (to disabling/enabling groups) is currently to create a number which represents a state in the event sheet. I personally find this a better way to understand/write non-trivial code.
Therefore it would be great to have enumerated types, so I can label the states in the event sheet and make it more readable.
