How to change the color / of tasks

Hi,
To add more lisibility I want to add some colors and Bolt on task view list, how to do it?

No such function in prgram, but something in xml file?

I am not sure that I fully understand the question, but anyway, you can change a task color in the Task Properties dialog.

yes, it changes the color of the taskbar, but how do I color the task name in the left panel?

No such option, sorry. But you can make the Task Color “column” visible in the task table. It appears as a small colored circle next to the task name.
