I'd love to see an add-on for Botania that added a dreamwood avatar. It should be able to hold three items, like one rod and a stack of blocks, or two rods, and the third slot on the head for whitelisting/instructions. Make it craftable with four regular dreamwood, one glimmering one (for the head) and a Gaia spirit. Give it the ability to hold buckets (extrapolated or regular), the Rod of the Shifting Crust (RotSC), a Wand of the Forest (WotF), or drop items. In my mind, it would have a hidden mana buffer that must be filled to perform any action, and after each action, it would empty (the buffer would be the size of a Gaia spreader's burst). It could right-click or left-click.
For an example use, it could be placed near a pure daisy, hold a RotSC, a Rod of the Lands, and be instructed to turn obsidian into dirt. A rannuncarups places a blaze lamp (pulse 2), the daisy turns it into obsidian (no block update), and the avatar turns it into dirt (pulse 3). An observer block checks each update, causing a pulse spreader to increment a hovering hourglass with mana powder. This then triggers a pulse spreader with a bore lens to break the dirt (pulse 1), and the cycle repeats.
Other than that, I'd also like to see a Gaia-spirit-ingot-bucket that, when linked in a set of eight with pixie dust in the middle, acts like RFtool's powercells, but for liquids, and only up to eight buckets worth. Fill one at an infinite water source, and the others linked to that one get access to that water.
