I’m an avid user of CLZ Books, CLZ Comics and CLZ Movies. It would be AWESOME to have a CLZ Lego! You guys are Legos fans as well - help us out 
Haha yes, the idea has come up a few times.
Not sure if it will ever happen though, we are quite busy with the 5 collection types we already cater for.
Funny about this… I created a new platform called miscellaneous, then a hardware type of lego. So, I add hardware manually and choose miscellaneous then lego.
With miscellaneous I can group many other things, like Sears catalogs under hardware type for that, or hint books, controllers, etc.
This also lets me track the bar code for the lego and other details. Some of these are on Price Charting which is nice.
