It would be awesome to filter the color palette by year to see what colors were
active. The introduced and retired data is already available on most colors in
the color guide, and it would be a cool way to browse the history of lego parts.
Would also really help in trying to collect particular eras of lego.
The catalog has long had the feature to see the parts intrdocued each year. What
is not available, however, is viewing all the parts in the palette for a given
year. Currently most parts have the year they were introduced and retired, but
the latter half of that data is not viewable in a list format as far as I can
tell. Being able to view the "active" catalog for each year would be
a great feature to browse Lego history.
This could also be extended to the other broad categories in the catalog, but
not sure the year data is as robust on those to be easily done.
A more complex version of this suggestion is that the active catalog view for
a given year should only include those parts appearing in sets for sale. Right
now it seems like the year data only accounts for the first and last appearance
of a part and not when it was truly active. But sets right now only have an introduced
date and do not have a retired date so it may be hard to figure out what was
actively for sale in a given year.
It would also be great to get as granular as the mold variation available, but
that is probably rather difficult with all the slight variations contained in
the same listing.
