Requested changes for configuration

[ewindahl]

@kushu493, this is a combo of requests from me and the configurable apps team. Thanks!

1. Config panel organization (to better align with existing apps):

• Move Search to own its own tab
• Move Enable Image Measurement to the Imagery tab
• Create an Options tab and move the following to it:
  • About
  • Basemap Gallery
  • Scalebar
  • Bookmarks
  • Export
• For options where only one field should be selected, change it from checkbox to drop-down to prevent more than one option being selected:
  • Imagery Layers (Image date field for each layer)
  • Imagery Layers (Search field for Image Selector for each layer)

2. Need to have default options selected:
Right now, nothing is checked on so if someone were to create the app and launch it there would be no widget available. Most apps have some default options checked.

• Layer Selector – this seems to be the most valuable tool in this app and the reason most would use this app. Is it possible to use these options as default?
  • Layer Selector: ON
  • Type: Single Layer Viewer
  • Layer (Left Image): Default to first available imagery layer
  • Layer (Right Image): “Select Layer”
  • Display: Slider and Dropdown
  • Imagery Layers (all): Off

3. Add “Specify active tool at app startup” option to Options tab:
(Also need to remove related checkboxes from About and Layer Selector)

4. Fix Editor tool configuration
When the Editor tool is selected and I have no editable layers, I get a message indicating I have no editable layers. The widget will still appear in the app. Would it be possible to prevent the widget from showing up in the app? Could the text indicating there are no editable layers be changed to red text?
