I've just been comparing 7 different portable burners & ImgBurn was the clear winner. Until I realised there's no multi-session. Actually, it's still the best but I now need to keep one of the others because I often need multi-session.
I'll gladly make a donation of your suggested $2 for it, as is, but I'll make it $20 if you could bump multi-session up your priority list.
I would suggest others with the same need should encourage/reward the author too.
Many thanks.
