What are the best aspects of this product?
I like the fact that there is a free version. After all, I use this tool to help manage my personal project (which some might find silly), so I was not looking for anything too complicated. MeisterTask has an intuitive UI that is visually satisfying and easy-to-use, providing me with everything I need (and then some) for a personal project manager.
What aspects are problematic or could work better?
I have not used the paid version, so maybe this is a thing in the paid version, but it would be nice to be able to set tasks as being either epics, stories, tasks, or sub-tasks. I know that in the free version, the checklist items can kind of serve as sub-tasks because checking them off displays on the main pane as 1/3 or 2/4, etc. depending on how many checked items are on your list.
What features/services would you like to see in future versions of this product?
(Unless I am mistaken and this is already a feature of the paid version) I think it would be cool to be able to integrate this application with something like Gerrit (which I use at work) so that tasks could automatically be moved from a section like 'in review' to another section like 'ready for QA' when the code got merged into master.
