Hi,
Since the beginning of the protocol many people have been asking about the LP price and it would be a great feature to add. Nowadays the easy ways are:
A) Provide new liquidity and see how many LPs you got from your $
B) Check your transactions
However, A is expensive and a headache in Ethereum because of the fees, and B is difficult if you have many transactions or it was many months ago
About the IL, it has been proposed by an user in the Telegram chat and it could be helpful, however I don’t know if it is difficult in case one has more than just one stake. It would be weird calculating the IL of different liquidities as it would be an average IL
