KatieB4: Why are ISA rates lower than savings rates? Savings rates are much the same, net of basic tax, so ISA is no real benefit
You are right that rates are disappointingly low ATM, however if you are saving for the longer term maybe in time rates will recover and/or tax rates will increase and if you haven't saved in an ISA you will have lost your tax-free allowance.
Regarding your last question, unfortunately not.
