Gantt charting is, if we are not mistaken, complete and the source code for Feng Gantt 10.0 will be posted shortly.
The sorting of all Workspaces, Milestones and Tasks/Subtasks now occurs correctly, by alphabetical, start/end date, etc. as appropriate.
It is unfortunate that it took this long, and that it does require the use of a handful of functions, stored procedures and temporary tables. We are not happy with the code or the mechanism that was ultimately required to make this work, but we ran into more than a half-dozen MySQL bugs during this process and we ran out of time and resources to continue trying to work through them - eventually we decided to take this route and work around them instead.
On the plus side of the equation, it is *much* faster than it was previously, and I have added the option for you to be able to display (or not) the Duration, Start/End Dates and Resource columns of the Gantt chart.
I will post the source code by the end of the day and update the instructions accordingly.
