Hi,
Glad you find a solution.
As for the timetable and priority list I don't have any detailed information for you. Acyba is focusing the entire year on developing Acymailing 6. They even dropped support for AcySMS for this. They have to recode ten years of coding and that's a lot of work.
The problem is that we (the users) all have different priorities and Acyba can't realize all of them at the same time. In general they focus on the most used features first. Though there might be situations where they work on specific features and add some less important features in case they are related and easy to implement.
The roadmap is gone, so we basicly don't know what they are working on and in which order. But be sure that all v5 features will come back to v6. Patience is a virtue.
