I think this is a good app and I use it a lot more than I expected. However, to make it really great, it could use more polish. Examples: * improve the data sheet viewer - it frequently blacks out and you have to go back and redownload them * the purchasing system could be a lot better- credit card entry is very 1990 and Apple Pay or even just a platform understood way to enter payment info would be great * searching is good and Im not sure how to make it better on mobile but Im sure it could be a lot better - please dont make it worse in the process * shopping cart doesnt empty after purchasing so you have to individually remove every item - maybe it can just copy to a previous orders list if it needs to persist
