while I use GANTT it would be great if I was not able to assign a task to a resource if the resource itself has on vacation. I mean, is it possible to introduce a bind that prevent from add a resource to a task if the resource is out of work or has scheduled to go on holiday? Is it feasible also to cancel an assignment made already if the free days insertion was done afterwards?
This is an old issue which is waiting for its own brave knight. Hopefully now when we get more donations we'll be able to find someone who will fix it.
PS. Gantt is a last name of a person . The software name is GanttProject.
