Blesta always needs to check you have a valid license. If you decide to sell it to someone else later, why should your copy of it continue working?
I don't play the lottery, but if I did, it wouldn't change anything. There may be more money to spend making it better though.
it would be nice and totally usefull to have filters in transactions page (billing/transactions/) .
some times we need to filter by a gateway, amount or by dates ... ect. with the actual view i not possible we have ony option to order by or search option.
