Title pretty much sums it up.
First request, that i think may help, would be been able to use the Alt+S search, that other Tabs have, to search on the Work Orders Tab.
Reasoning is that, sometimes, we may forget if we put a work order, and don't want to make a duplicate.
When you are on a early-mid or Late game, the Work Order tab normally is so full, that it's a time consuming thing to search manually.
So if possible, this would help a lot!
Second request. One big problem of the Vanilla Stocks Tab, that i noticed is that, let's say an rock block/metal bar is not separated between one used on a wall, and one sitting on a stockpile.
If a filter could be added, that allow us to see how many "X" item are already used on a construction.
Another option that could be interesting, is a toggle that add if the item is and what stockpile it is on.
Overall those two tools, could enhance the experience, imo.
On an ideal world, those would be baked on the Vanilla game, but they are working hard on so much, that filters like those, i imagine would be low priority for them, specially with the rewrites and remakes they seem to be focusing, that will give actual new ways to play the game, instead of small QoL features.
