Hi MarginNote’s Support Team
A main requirement with business is growth, and lack of growth allows competitors to catch up. MarginNote is most likely dying, and here is why.
You have two major issues. The first is lack of resources, one developer only for such a project is a joke - so you need to get funding/sponsorship to employ more and there is no reason why you should not be able to do so with such a good product. Second, the design needs reconsideration, it is not intuitive at all and there is a significant learning curve which ultimately pushes users away - so you need to reconsider design aspects.
You will know that LiquidText is a competitor, and it has limited resources also and frankly much less breadth of capabilities. But it is amazingly intuitive and more stabe which makes it much superior option. With a Mac and Windows clients in the making, it will hit you hard once these are released (assuming they do it right). They are making baby steps, but steps they are and as such offer better potential.
Users will ultimately have to make a choice, because users invest in using a package and change is not an option. So few weeks ago, this user made his choice and switched to LiquidText after years of patiently awaiting your change and noting your apologies. It was a hard decision and unfortunate, but I can see much better potential in that direction to invest my time and effort.
Hope you find the above thought provoking, and good luck with you journey.
