Ratings and reviews

Nice app, thank you! Pleeeease add older sets. Should be easier, as they are fewer and simpler. Right now I can't add most of my sets and wanting to add my space and Technic Lego! Also, a sort and filter functionality would be nice, and there is no cursor in text boxes! Overall still feels new and unpolished but lots of potential. Should be 3 stars, keen to give 5, giving it 4 for potential !

Needs to have the ability to select pieces that may be missing from collections as you go through the builds to add to a list and then be able to order those pieces missing. Even if it's just the pages of the itemised pieces at the end. To be able to select each item and add that to a list. And then print that list off.

Everything was working great until I made an account and attempted to log in. Spent several hours adding all my sets into it (though not happy that there's no catagory for 3in1 creator sets), so I thought I'd save my progress by signing up for an account. Once I tried to log in, it froze. I closed the app, reopened it, and now can't get past the second splash screen. Several hours down the drain then. Thanks for that!
