It would be nice to have an electric version of the sf composter, which turns stone into netherrack and, more importantly, sand into soul sand. The main use of this would be to streamline the production of quartz, which can currently be done by creating sand from the igneous processor, manually converting the sand into soul sand in the composter then using an electric gold pan on the soul sand to turn it into quartz. This would also be an easier way to farm sulphate.

Related to this suggestion, the composter can currently turn 8 leaves or 8 saplings into 1 dirt. It would be convenient, and would reduce terraforming, if this recipe instead produced several dirt blocks per leaf block or per sapling.
