Allow the option for developers to add hover-over text/tooltips to images.
What is the use case?
I can envision a number of use cases for this, but the primary use case for us in the immediate term would be to include either a question-mark or lightbulb image on our dashboards that when hovered on shows information about the dashboard content calculations (without just putting a full text box on the dashboard).
This would be similar in functionality to when you add a “Set Description” to a column header in a table (but very preferably more than 200 characters!).
How often would this feature be used?
This would be used on every single one of our customer-facing dashboards and on most of our internal dashboards.
What is the impact of this feature on your organization?
I have used this approach in other tools and have received great feedback from users. This would be a major UX enhancement for our organization.
