Feature Request: Simultaneous Character Reveal

[Hsgngr]

Description:

It would be great to add a new display mode that reveals all characters at the same time using a simple trick:

Currently, when displaying a word like "COW", each module rotates individually to its target character. Since characters may require different rotation distances, the word can take a while to appear completely. By the time the final character finishes rotating, the word is already predictable — which makes the reveal less exciting.

Proposed Enhancement:

Reveal all characters simultaneously:

• First, rotate all modules to position -1 (one step before the target)
• Then, trigger all modules to perform one final step at the same time
• Example:
  • Target word: COW
  • Pre-step characters: BNV
  • Final step reveals: COW

This creates a more synchronized visual effect.

Implementation Question:

To implement this, I need a way to determine when each module has finished moving to its pre-target (-1) position. Is there already a method or flag in place to check if all modules are idle or done stepping?

Let me know your thoughts — happy to open a PR once I get the green light or some pointers.
