I believe it would be very useful to integrate a function that will allow the matching of display properties of backround and font colour in the Gantt (something similar to the brush tool in Word).
This would allow the user to set the display properties of the activity and repeat/match others with it much easier than going back every time to update manually.
Finally, a "set to default" function to reset the colours in Gantt would be helpful. As Synchro is now the user needs to select all modified tasks and manually go back to defaults, which is not very user friendly in very large programmes.
