How can we improve Application Insights?

String comparison within JSON objects

I am logging entire JSON objects and I would like to query the API based on attributes of these objects. For instance I am logging request headers to the database and when I query the API I want to query something like:

traces | extend properties = customDimensions.req_headers
| where properties.["connection"] == "keep-alive"
| project timestamp, properties

Right now I am getting 0 results with that query. It is possible to click a small "+" button next to my "connection" field of the JSON object which adds exactly the line
| where properties.["connection"] == "keep-alive"
to my query so I presume that this feature is going to be implemented in the release version? Is it going to work with more nested Strings as well? For instance properties.["myObject"].["otherObject"].["attribute1"]. Such a feature would be very handy.

    This is effectively asking to use App Insights as a general-purpose Document Database, with automatic indexing on arbitrary properties. Right?

    'It is possible to click a small "+" button next to.......'

    It is no longer possible. You can still unfold JSON documents in the UI, but the button does not appear next to the properties within them.
