@joywind: I suppose this tool is not designed for planning, but for reporting. Too bad it doesn't match my needs. Moreover, i see that tasks can live on the same row, but they cannot touch one another, when you try this the task you are working on jumps on another parallel timeline. This doesn't fullfill my need of "stacking" tasks. This is not vital anyway. The mosto noticeable missing feature is the auto recomputation.
@elvisbrown: This is a really complex tool. Nothing against it, it looks complete and full of juice but it's not possible to decide the order of tasks. Yes you can, but only by tewaking the priority field. And there is not recomputation of dates by rearranging tasks.
Both tools work "upside down" respect of my needs. I mean: both need a "start date" and a "end date". To refactor i need to accomodate the start date and end date of all tasks (by dragn' drop or other means, but all of them need to be arranged manually).
On the countrary, i'm looking for something based on "the length" instead of a couple of dates. I know how much effort a task will need from me, but i don't know when i'm available for that effort. And i accomodate manually the order of my task list until i see a good result for start/end dates.
I seen there is a "budget" field in TaskCoach, but it looks somewhat separated from the core part of the planning.
Again, thank you for your hints. Umberto
