Hi Larry,
I'm a GIS Developer and I really like your Print Plus widget, however we need to overcome some issues after we customized the widget to show just two scales 1:24,000 and 1:100,000:
1. When the frame is set to 1:24k and the user zooms in past the frame, it will return to view upon zooming out. But, when the scale is set to 1:100k, the frame will not return to view. The "Show Layout" toggle has no effect. Only resetting the scale will restore the frame to view.
2. When the “Show Layout” toggle is off, setting the scale will return the frame to view, leaving the toggle unchanged. When the frame returns it will no longer remain stationary when the user pans from inside the print frame but will move with the basemap as it would be expected to do when the user pans by clicking outside of the print frame. Neither toggling the value of “Show Layout" nor setting the scale value will restore it to working order. The app must be reloaded for the widget to return to normal.
