Here's what could make the simulation much better:
- Seeing inside chips
- Editing chips
- Delete Projects
- Saving incomplete chip designs
- Tabs so that you can switch between incomplete chip designs
- Zooming in and out
- Tri-state logic
- Read Only Memory (Nice for segmented displays)
- Inputs and outputs on the top and bottom of chips
- Ability to adjust the clock speed
- ASCII character display
