We do listen, trust me, we do. However, we do not have unlimited resources, and must prioritize. We may not agree on the priorities, but that’s up to us. Or to you – AxCrypt is open source, add the feature you want, or pay someone to do it for you if you don’t have the skills personally. Then ask us to add it to the product which we may do if it’s a good change or for example something on our own to-do list that you just can’t wait for us to fix.
