For a start, you could restore the Gantt functionality that disappeared when JCVGantt was ""integrated"" into MindManager. JCV wasn't the greatest Gantt program in the world but at least it had things like critical path, some resource management ability and it was also possible to develop add-ins for it - all features which have been lost. And being a separate program meant it had its own window which you could run on a separate monitor - even on my 24"" it's a struggle to look at it in the same window as the map.
The other problem that occurred when it was integrated was that the fixed relationship between start date, duration and end date which JCVGantt had (as do most project management programs) was forced on MM to maintain compatibility. This screwed things up for a lot of people who (like me) wanted to set a task completion date in say a week's time, even if the task needed only one day to finish.
So, basically JCVGantt went from being a modestly capable project manager to being merely a Gantt display for MM, while time management in MM lost a lot of flexibility. Exactly the same sort of dumbing down appears to be happening to Power Markers where after its ""integration"" the more complex features are not provided in MM2012 and we are left only with the marker index display (and yes, I know they are available in the add-in pack, but only on request).
To be frank, I've got to the point where I no longer want to suggest that Mindjet incorporate good add-ins into MM, for fear that their most useful features will disappear in the process." [from Alex]
