As a crypto investor, not a tech enthusiast, much as I like Litebar,

I don't want to buy any unless PoS is added. Bitbar is more investor-friendly this way, as is LitecoinPlus and BitcoinPlus. Dev, there needs to be incentive for people to buy and hold. If the intention really was to be the silver equivalent of BTB, I think PoS is essential.
Adding PoS is planned for litebar - but it won't be until towards the end of the year, or possibly the start of next year.
You can't just copy/paste it into the code - the blockchain doesn't have the entries needed for pos, so there is a lot of work involved
