When I am looking at large canvas apps, it is difficult to find out what the type is (collection, variable, datasource) and finding the right area to navigate. It would be good to display a navigation link on the formula itself - a sort of go to definition. In the example below "ConnectionDefinitions" is a collection. Two features would be useful:
Ctrl-Click on "ConnectorDefinitions" takes me to the collection itself
The type is displayed in the autocomplete. Instead of displaying "ConnectorDefinitions" below FormatText, Remove Formatting links, display "ConnectorDefinitions Navigate to Datasource" (if 1 is implemented, hyperlink is not neccessary, instead display "ConnectorDefinitions Datasource"
