Aye, a category would give a handy hint (I pretty much never Extract Plants To Vial until I get glassworking online, which means Magma Workshopping up and running in my case, because I have an early-game blindspot about other-types-of-'vial') and might encourage consistency.
Chain and rope pages are practically identical separate entities that state that the other exists, with a link across in both directions, whilst others redirect everything to the Ur-example page with
either tabular or longhand plaintext explanation of the material/name relationships. I imagine everyone has their own favourite way of thinking of these links, so won't suggest which way would be the best way to make the result consistent (whilst maintaining source-material differences appropriately). (Obviously with mugs/etc as sub-headed within Finished Goods, it'd be impractical to split out Mugs/etc into separate-but-linked pages, so that suggests the direction, if not the final presentation.)
A handy Template construct for a comparison table, would be my next suggestion, could be used for "Can you make a Foo out of a Bar" reference (single or multiline, in addition to headers), another handy-lookup reference material that I keep on meaning to make myself instead of relying on memory.
It's not even as if the game is internally consistent in handling of 'groupings'. Within the Conditionals for a Manager/Profile job, the default post-requisite check for all containers of all kinds works on the generic "boxes and bags" category whilst the same check for other things that have equivalents appear (may or may not be functionally more broad, untested!) to narrow down to the specific subset being requested.
But, then, consistency within the
game is an oft-mentioned issue. Which is of course why I still go looking at the Wiki every now and then, even after all these years, to at least jog such vague memories.
But really, I just thought that someone else might appreciate the info gathered together, somewhere it could be sufficiently curated to take new additions at a later date.
