making mass fabs self-toggle to avoid power stalls seems like a great addition to the base game,
after all mexes, pgens and ras never have this problem, so fabs have this unique disadvantage.
i would like to make a distinction between t2 and t3 fabs however, since t2 are usually just used for eco production, whereas t3 can also have significant use for the adjacency discounts, however this is only in effect when they are running, so having a toggle between priority for these would be useful !
Also I use Ecomanager mainly for the mex and silo overlays, and the right click on mex, and only the fab manager portion for the 'eco' side of it, which i tweaked to prioritise t2 fabs.
So if the change to the base game comes in and the economy-wide toggling is removed, which i support since it acts as a brake on newer players learning to manage their economy and also seems to give an unfair advantage in some lategame situations, then having a stripped down version with the parts players use and like should be available.
