So from here...
Hi James,
thx for the screenshot. I was worried that the whole connection string would show up in the tab title after your initial description. Thankfully it does only show up in the ad hoc computer name field which is by design at the moment.
For the next update, we'll not put the connection string into that box however if you pass it via the "rtsx://" URL scheme. So that should fix your issue.
cheers,
Felix
James
