Add option to display popups in sidebar in Web AppBuilder

[KeithGerhartz1]

The standard popup obscures underling information. It would be really useful if display position could be set within the popup configuration as one of:

1. Absolute position on screen 
2. Position offset from feature

3. In a sidebar

Robert Scheitlin's Popup Panel Widget is great and is well received which indicates a lot of of interest. However, it does not support related tables and exhibits some unpredictable behavior. 

This functionality is suitable for inclusion in the standard product offering in my opinion. Any others want to chime in?

[HURIGIS]

yes, I'd like to see this feature added too.

[NancyDees]

I would still like to see this feature added.

I would really like for this feature to be added.  The options to get it right now are less than ideal.  If ESRI supports it in existing instant app templates (see Sidebar template for reference), there's no reason it shouldn't be included in the standard version of WAB.  I don't want to have to host my apps outside of AGOL, and I have similar concerns about the custom popup panel widget referenced by the OP.
