TL;DR

The rocket silo should have a circuit option to output current rocket build percentage, optionally the secondary rocket as well.

What?

Image mock-up, rocket build progress could be output to the circuit network (likely as a user-controlled signal, like assemblers and roboports).
Shown as a simple lamp progress bar under the silo here, but could be used for alarms (progress hasn't updated in x time?) or manual loading aid with multiple silos (avoids needing to click in to each one to check).

Why?

This small feature would positively impact the game by allowing for more functional and aesthetic builds around rocket silos, rather than only visually changing once ready and at launch.
While this feature would be mostly useless in the base game, silo progress is an integral stat to manage in space age.

A very simple way to get some extra functionality out of what's now become a very important block
