For those of us that run a shop with the inventory storage based on the BL catalog,
it can be a puzzle when items get moved to a different category.

Internally we have a web page that shows items that have moved. Would that be
helpful for others as well? See this link:

Currently I have it limited to only pick "parts" or "minifigs" - in the last
month there have been an _insane_ amount of category changes for gear/sets/instructions
etc.

That is a wonderful tool and thank you for sharing it. BrickLink should absolutely
have something like that on-site: an easy-to-read, well-organized tool with pictures
which show when stuff is moved around and where it has gone.

  Currently I have it limited to only pick "parts" or "minifigs" - in the last
month there have been an _insane_ amount of category changes for gear/sets/instructions
etc.

This was the result of categorizing the 700+ items which had no categories and
these were necessary changes. I expect additional changes to occur in the future,
so I have saved your link and will share it again in the future if you don't
mind.

If you could figure out a way to add sets and gear without overwhelming your
tool, then that would be awesome. At some point I plan to go forward with precise
written definitions of all item types (I actually have them written now) and
when that occurs it may be necessary to move some items which don't fit the
definitions.

This, for example, is self-evidently not even remotely close to being a set:

[S=bb173-4]

It's a storage bag and it will be moved to Gear when clear definitions of
item types exist.

I use the BrickStock database to identify category changes. However, it won't
work for items that move to a different type (like your example). Reason is that
the BS database doesn't have unique identifiers for each item - my program
figures out any category changes by checking if there are such changes for partnr/type
pairs. I can't track changes across types of items, as there currently are
already items with the same nr in multiple types (and that wouldn't even
take into account the fact you will likely change the part nr in that example).
