Manually taking snapshot images of sheets to provide professional looking app overview sheet content has a number of problems :
It takes time
Not all users have the skills to produce consistent image files
If the sheet contains conditional content e.g. section access based, then the manual snapshot image might reveal sensitive data
The media library needs managed
Every time a user edits a base sheet the image is out of date
Version control of the images is needed in an enterprise environment
When a user duplicates a sheet and works on the private copy the new copy also needs manual work
Qlik Sense produces a grey version of the sheet layout in the thumbnail by default. Can this be made cleaner and can the sheet image be captured automatically in its glorious user-facing state - 100% dynamic too ?
