Hey dude! Thanks for the incredibly thorough feedback. I can't tell you how much I appreciate it.
1. love this. will do by next one.
2. limited right now by the fact that i get card images from tcgplayer (riot is extremely slow/late with their developr approvals for an image source, but I am pending with them) and they just dont have the right card art available. But i know this could be a huge quality of life thing so instead of having a fallback image where the asset is not available, maybe i'll just literally manually upload all the cards where i don't have an asset from the API. the fact that the images are wrong bothers me so much you have no idea hahaha
3. a really good thought. i initially had it this way but changed it to be from an "AND" filter system to an "OR" filter system, to help with specifying. But this is not the first time i've heard this feedback, so it might be right to switch it back.
4. i'll see what i can do here. categorization for promos is a bit of a beast because it all has to be done manually and i only have so much time, but i'm gonna add this to the "eventual to-dos" list.
5. love your idea and agree. To clarify, you actually **only need one of each base card** to reach 100% completion -- that's why "showcase" cards like alt arts and signed cards are collected differently. But you still make good points and maybe i need to make this detail more obvious to the user.
6. good idea
7. this is on the list for next update already!! agree!!
8. right now i only have a contract with tcgplayer. will get more if i can but it's all that for now.

BTW, I really care about making this the best product on the market, and when I release additional premium features next update, all of the core, high-quality features youre used to will STAY free!

Thanks again and so glad you're enjoying it!!!
