How do I make a gantt chart usable?

I convert my OKR table to a gantt chart and can’t see the text in the left column at all, nor can I read the text on the colored bars. Can I make it wider and change the colors?

Dear @Per_Bonomi,

The options for the charts are still limited and like many others, we cross the fingers to get soon a more rich experience.
The size and color options are also limited.

Depending on your use case you might consider to embed Miro
