Hiding new task buttons in Gantt chart

Hiding new task buttons in Gantt chart

In Projects' Gantt charts, the left column looks like this:

First milestone
___Add task list
Second milestone
___A task list
______Some tasks
___Add task

Is there a way of hiding the orange buttons for creating the tasks and tasks lists? For me, they are a serious readability problem for the left column of the Gantt chart, they introduce a lot of visual noise. I don't use the Gantt chart to create tasks, only to see dates and dependencies.

If there's no way of removing those buttons, I'd ask Zoho to add such an option.

Alternatively, instead of hiding the buttons altogether, they could be reduced to icons and put in the same line as the milestone/task list. What I want is that those buttons don't have an entire line with a long text in a flashy color.

Is this possible? Thanks!
