We're glad to announce GanttProject 2.8.5 which comes with a new feature: task ordering by begin/end dates. The feature itself was highly demanded, but what makes it even more exciting is that it is the first published feature which has been contributed by external freelancer and funded by the donations from GanttProject users. A number of other paid features is already done in the main branch and will be published in the next major update.
If you love GanttProject and want new features to be added faster, donate as much as you want!
The sort order is partial. Sibling tasks are sorted, while tasks from different branches of the task tree (e.g. sitting under different summary tasks) are not necessarily sorted. For instance, on the screenshot above milestone "GanttProject 2.8.5" goes below the child tasks of "Architectural design", although it starts earlier. The order is indicated with an arrow in the column header showing upwards when order is ascending or downwards when it is descending.
Sorting should work as expected: click the column header to sort in ascending order, click again to toggle to descending order.
Sorting is not maintained continuously. Any actions on the tasks such as insertion of the new task, reordering, indenting and outdenting may break the sort order. One needs to click in the column header again to restore the ordering.
Besides the new feature, GanttProject 2.8.5 fixes a few severe bugs and updates Korean and Dutch translations.
