It would be great to have a new widget in the web-app builder, that is simply for the Pop-Up box infomation.
To enable users to effectively 'dock' the pop-up box into a panel rather than it appearing on the map.
To take it one step further, my next request would be, if the search/click results in more than 1 feature being selected/identified, that rather than just showing the first feature, with a tiny arrow and (1 of...) in the top corner - that instead a list of matching features is shown first (user to configure which attribute is used to identify) and then from the list they can quickly bring up the one they are interested in, as opposed to having to scroll through all the results.
