Aligning Categories to user expectations

[Chris Dee]

All fixed and parts fast-track certified, with the exception of the following which need a little more thought:

Code:

[b]Unofficial categories implicitly defined by the first word in the description (from parts lacking a !CATEGORY)[/b]

[s]Cockpit // why is this not an official category?[/s] Created and parts categorised

[b]Bizarre official categories[/b]
[s]Gate (fence, door)[/s] Done
[s]Jack (Minifig Accessory)[/s] Done

[b]Weirdly filed parts[/b]
87747 "Bar 0.5L" but in Minifig Accessory
[s]4628 Jack Handle in Minifig Accessory not Jack![/s] All are now Minifig Accessory
[s]87614 "Tail 12x2x5" but in Plane[/s] Done
4876 "Fabuland Slide" in Staircase // why do Belville, Scala, get categories but not Fabuland?

I agree that Duplo is a mess, but I'm not convinced that dumping everything into one Category is good either.
I agree that Belleville, Scala and Fabuland should be treated similarly, but it is hard to define what is and what is not primarily a Fabuland part. The Shovel (556.dat) that has "Fabuland" moulded on was used in two Model Team sets and a Belleville set.

Suggestions for the other unsolved issues are welcome.
