Tooltips on click or hover#499

SImple. The ability to use tooltips on data in cells, accessible by hover or click.

There have been quite many suggestions and upvotes on this subject, I’m also hoping this would make it into their roadmap soon.

In addition to data cell tooltips, there are users (such as me) who would like to see the tooltip possibility when editing or adding data, to provide tips and instructions to editor users.
