Quite frankly, I'd prefer a complete separate GP widget like we used to have in the WAB.
I have a few GP tools requires drawing points and polygons on screen to select data for analysis. The GP tool implementation in WAB works perfectly. I found a number of functions are currently missing in the Analysis widget to migrate successfully:
1) limit drawing options to GP tool supported geometry only - the Analysis widget show all geometry types in drawing tool
2) allow symbology selection for input geometry (including features created by drawing tool) - critical to drawing different type of feature points in an isolation tracing workflow, otherwise they all look the same on the screen
3) need a Clear drawing button to clear drawing features on screen
4) The drawing tool on Analysis widget stays active even after the widget is closed - need to reset it to default cursor after user closes the tool
Thank you!
