While we're talking scale bars... Let's say you zoom out to a continent. Where is the scalebar accurate for? The equator? Middle of the map? It would be so neat if Esri came out with a variable scale bar or more sophisticated measurement tools. This would be a custom widget for us to specifically enable or include of course. Or perhaps a little button to click that would switch between geodesic and planar for measurement (thus exposed to the user).

Please fix/do these asap. Thanks.
2) AGOL only supports simple symbology - 'many fields' symbology is not supported. Layers have to be broken out into component types and then symbolized using simple symbology. Not ideal.
3) AGOL (Web App Builder) does not allow all layer labelling to be turned on and off with a simple icon or widget – this would be very useful.
4) the text colour for the scale bar (via the 'Scalebar' widget in Wep App Builder) is grey and cannot be changed. Grey is illegible over the aerial photograph basemaps. Please offer other colours.
5) the buffer in the 'Incident Analysis' widget (Web App Builder) is a transparent grey and cannot be changed. This buffer is hard to see over aerial photograph basemaps (the preferred basemap for our web apps). Having choice to change the colour or simply do an outline with colour and line width options would be very good.
Have I just been unable to find it, or is the scale text actually unavailable in web appbuilder?
I rarely create a map that doesn't include "Scale 1:#####"
The tiled basemap zoom levels all have specific scales, so they should be able to be displayed as you zoom in and out. (either part of the scale bar widget, or a separate one.)
They show absolute scale on the printout but it would be nice to see under the actual scalebar in the viewer. In fact, it would be nice to be able to click it and tell the map to go to a specified absolute scale, like 1:500 for example. Sure the tiles are at particular levels of detail but the server could re-sample and spit them out at whatever level is needed. (if they would enable that in Enterprise and make it a default behavior for tiled imagery that would be great, especially so we do not have to tile down to 1:72, 1:141 etc which is another Idea I have made)
This works fine using the Advanced trick in Print Widget to zoom to a specific absolute scale. Though it only works in the actual PDF that gets created by Print and not the map viewer itself. But this should be more discoverable. There are a lot more engineers, architects and surveyors than GIS analysts. They want this. Even lay users would understand this. Would be very useful to simply let users type in the absolute scale right under the scale bar. Very useful to users; very easy to implement. No reason not to let users specify an arbitrary level of detail / scale. Long ago with tiled basemaps that would even be possible, the tiles could be resampled. Now with vector basemaps they will look good at any scale and even more reason to add this at as an enhancement at some point.
