For custom fields with the type “Predefined choice list”, improve the readability of the “tag” style texture by either making the surrounding shadow pure black (instead of a light gray around the characters), or remove the tag texture and just use standard text instead.
In the printed version of the Notebooks PDF export, the grey shade around letters reduce readibility greatly.
Most computer-savy audience will log into Aha and use the interactive webpage, or view PDF on screen, which allows them to get around the low readibility issue by zooming.
The less computer-savy audience depend on the printed PDF.
Unfortunately my senior management group falls into the less computer-savy group, and they decide whether Aha can be adopted at my organization. The readibility issue would likely lead to a no-go.
