I've been using, although not consistently, MLO for a very long time, version 1 I believe. The lesson I learned is that development is very, very slow. Right now, the focus is on ios as that is probably where the ROI is greatest. They never commit to a date. If you're not happy with what is available now in the app, best bet is to look elsewhere because change is at a snails pace.
I like MLO and if it finds a home with a developer with more resources, I think it would be a really nice cross platform app. I think it is too slow in getting the features across platforms to be a relevant player in any platform because once they start putting resources into android, ios development will suffer and fall far behind; who knows what's going on with Windows. I've pretty much moved on to todoist because MLO doesn't work well with Windows tablets and I'm not going to wait for them to fix the touch response of the program for the least likely platform to see changes.
Android and ios change much faster than the developer can keep up. The program does the job but the features and interface are always going to be dated if history is a lesson.
