Today, I decided to start posting ideas for modifications. Perhaps some of the modding enthusiasts will like something, and they'll be able to implement the idea in code.
The idea for modification is as follows.*

Briefly.
It's proposed to speed up the very beginning of a game by reducing the initial base construction time. This idea is an advanced version of the "prebuild" option, which is highly questionable and rarely used (and then only in modifications). It involves adding a temporary buff to commanders – the ACU.

Why? The modification will speed up the most tedious and boring part of a game – the use of standard initial construction patterns, repeated from game to game.
And it drags on for a long time.

Here's how it looks from the player's perspective.

After the "transition" effect, a boosting effect is applied to the player's ACS.
Similar to a temporary shield that flickers for the first few seconds.
The name is tentatively "one-time consumable kit."
This kit provides a temporary boost to construction power for the first few seconds of its action. It grants x7 base construction power, and then decreases over time (approximate values; balancing is required).

Important: the effect's duration is only consumed during construction or assistance.
More precisely, the duration and decay rate of the effect must be adjusted so that it ends by the time the minimum base is completed (approximately: 1 factory, 4 extractors, 8 generators).

The player's perceived strength of the temporary effect should depend on the remaining duration. The buff decays smoothly (not linearly) or in stages (there are quite a few time intervals; the shorter the remaining duration, the longer the duration).

The main condition is that the engineers who appear must be able to compensate for most of the buff's loss. This prevents a sharp drop in overall construction power after the effect wears off.

I hope this proposal will appeal to enthusiasts.
Thank you for your attention.
