How are objects ordered?

[JosiahH]

What are the rules determining the order in which things appear on the "objects" display?

[LittleSoul]

It seems to be by order of what you drop first in descending order. Everything you drop goes up in the list. For fixed objects I would assume it is ordered either by when it was made, and/or its category (ie: machines, furniture, etc)

[EchoMan]

First they are ordered by type (noticeboards, notes, raws, tools, machinery, etc) and then by their age (I think).

If they're all similar objects it depends on the order you drop them or move them into a room in. I grew herbs for 10 IC years, all the herbs, and dragged them out of a room and all back in again in reverse alphabetical order so they were displayed alphabetically. Including dried herbs. I was a special little newbie. When you add to a pile of the same resource, the pile doesn't move in the list.

Whereas tools seem to have a somewhat set order in terms of being sorted by type. But it might be that within each type (stone hammers, for example), they are ordered with whichever one was created most recently above the others?

How would different types of fixed storage be ordered? E.g., I have a room with a bunch of bookcases in it. If I built a container, will it appear at the top of the stack of fixed storage objects, or at the bottom?

Somewhat related: both bookcases and display cases can now be re-organised.

I think new things usually always appear on top. It's like that with noticeboards, bookcases, quite possibly everything else too.

In my experience (i might have missed something):

1) Notes. Ordered by time of creation, newest on top.
2) Resources. Ordered by time of creation of piles (adding a new type of resource to the location creates a pile, picking up the whole pile deletes that pile), newest on top.
3) Holdable items (tools, envelopes, parts, clothes, etc.). Ordered by item type code in the database, lowest (usually oldest) on top. If there are more items of the same type, those are ordered by creation time of the individual items. Envelopes are ordered alphabetically by title (i think, not quite sure).
4) Fixed items (machines, containers, furniture(?)). Ordered by item type code in the database, lowest (usually oldest) on top.

I have experienced about the same behaviour for inventories (cat. 4 is not there), with occasional exceptions in the order of resources held.

It differs depending on where you look, containers are different from the floor or the inventory. For example, notes in a container will show up in the reversed order of age with oldest on top.

I have this beautiful fantasy of one day being able to reorganize things in buildings, containers, and inventories the same way we can in envelopes and bookcases.

Display cases (and pedestals etcetera) were only recently added to the list of sortable items, but once it's been thoroughly tested it will be enabled for the rest of the world. Make sure to report any issues you find.
