I am rebuilding a Web AppBuilder app from ArcGIS Online to an Experience Builder app in our local Enterprise (version 11.5).
Our clients make heavy use of the Coordinate Conversion tool. It looks like the updated Experience Builder tool has some nice new functions, but is missing other important functions from the WAB version, namely:
The WAB tool allowed setting the number of significant digits in the results. This is very important to our clients. I don't see any equivalent in the EB version of the tool.

In the old tool's 'Add Point' function, the point would clear once the user closes the tool panel. The point does not clear when the new tool is closed, it seems to just stay there indefinitely until there is another search. This is less important but a bit annoying for the clients. Even is you disengage the 'Add Point' button in the panel, the marker remains.
There are a few other requests the client has made , such as displaying the business name and address when a business is selected, but that is less important.
