I love this but there are 4 things I'd love to see in the future:
- Grid snap, even with SHIFT being able to create straight lines I struggle to make it look good. Maybe having the grid line up with the size and spacing of the nodes on functions.
- A controls screen. I was able to figure out all of the controls after a while of playing and reading comments but I feel that the instructions page should explain that to make things easier for new users.
- Deleting, editing and previewing functions. I know this has been said a lot already but I still agree that it should be added.
- Finally, I'd love to only have to right click to delete things. As said by someone else, it's weird reaching over to the other side of the keyboard just to delete something.
