And a find & replace feature would also be very helpful.
Ah, yea. Find and replace certainly would be helpful. I'm hopeful code hinting is coming. Painfully slow to do programming in the interface. I know, it's an animation program, but we promise to misuse any application you put in front of us.
Another useful feature would be retaining, from one opening of the code panel to the next, the state twirled up/down of the symbol folders.
Now, by default every folder is twirled down. When the project grows, there are symbols with great number of handlers that are ok and could stay twirled up. It's not very user-friendly being obliged to twirl up again and again the same folders to go back to the piece of code we are currently finalizing.
