Opening a blueprint appears to do nothing if you have no rrd files

We are dependent upon the existance of Recordings to manage whether an app shows up in the recordings.

However, if I open a blueprint, I expect to see the app show up, regardless of whether I have any recordings.

In other words, you want to see all app ids in the blueprint panel, regarless if they have any recordings or not? What if you open a recording and close it again, do we still show the app id? Or do we throw out the blueprint once we close the last recording using it?

If we make app an explicit, selectable concept rather than an implicit grouping of recordings I think it warrants its own close button somewhere.

Suggestion:

• Switch to the app id when opening a blueprint (even if it has no recording)
• Show all known App Ids in the Blueprint panel that has at least one blueprint OR recording
• Close all blueprints of an App Id when closing the last recording of that app ID
