If I inspect the connector and then close it, I'm out of the connector list and have to select a type again:

it should keep the list where I clicked the Inspect button open.

there used to be icons here?

if I add connectors, connect them, then refresh, it opens the drawer again even though I closed it earlier:

I think the > should not appear as long as we havent selected a connector type (and have a table view)

lgtm aside from comments above

[Karakatiza666]

Fixed closing popup not returning to connector list (bug in production build).
The icons missing (Firefox only) and drawer opening on reload is a regression from another commit.
