Cannot add grey hidden columns (MacOS desktop app)

[Filippo_Galimberti]

Hi,

I just started using GanttProject desktop app for Mac and I find it really easy and intuitive to use. I just can’t add grey hidden columns into my Gantt chart.

I read on previous threads that I’m supposed to click the button “show selection” but I cannot find it anywhere (see the screenshot below).

Is there something I’m missing?

Thanks a lot for your kind support.

Filippo

The user interface of this dialog was changed in GP 3.2. TL;DW: click the eye icon.

Meet GanttProject 3.2!
