 ## Context
 
 - stacking ingots is a little odd, they dont stack neatly. so putting them all in the same place means it will get full but have lots of air space. what can we do about this? WHat in real life might be the solution for storing ingots?
+
+## Subtasks
+
+- [ ] Bars that come to rest snap to a brick pattern, so piles have no air gaps
+- [ ] Bar rack machine: takes bars from a belt or tube, holds a set number, shows the count, F lets them out

 ## Context
 
 - instead of buildings like the refiner which have a fixed size hopper, just make a block the same size as a wall tile that looks like grinding wheels where the user can place multiple side by side to create a wide hopper. the same thing should be done for the other buildings like that.
+
+## Subtasks
+
+- [ ] Grinder block (does what the Refiner does) and Saw block (Stone cutter), 1 block each; side by side they make a wider, faster hopper
+- [ ] Refiner and Stone cutter leave the build menu; built ones in old saves keep working

 ## Context
 
 - lets rework the vacuum/blower tool. the selecting, ticking, etc of the items for filtering and otherwise. its a little confusing and difficult to understand. lets ocme up with a simpler ui/ux, intuitive while still containing the same core functions like filtering what you pickup and drop and allowing pickup/drop all or filtered.
+
+## Subtasks
+
+- [ ] Bag rows get separate pick-up and blow marks (no more shared ticks)
+- [ ] Tool card chip: pick up everything / only marked / same as the first click
+- [ ] R over a grain toggles its pick-up mark; blowing uses the rows marked to blow
