So my installation has a variety of apps and sheets. Users have complained that they all look the same, and that navigating to and fro their favorite apps/sheets is more burdensome than it need be. I generally take a screenshot of the sheet, and make that the preview image of the sheet. The first sheet becomes the thumbnail of the dashboard unless I have a more relevant image.
My question is, is there a way to automate or quickly take sheet snapshots, and set that snapshot to be the thumbnail of the sheet?
I'd rather not have to do something so awfully tedious and relatively low value.
No, there isn't. And sheet snapshots aren't that clear anyway. Custom icon like images that clearly indicate the topic/subject or purpose of the sheet work better. Yes, that's work, but proper design and good visual communication simply requires some effort. It's part of the job of an QS app designer.
