I also considered extending `PanelCreator` to `PanelListCreator`, similar to how window lists are handled.

The first panel could be used as a split panel. (Two splits are possible but will it be good?) Additional panels would be converted to `JDialog`s like it's done for a single panel if split UI isn't enabled.

However, I'm unsure there's a use case for that. Using owned `JDialog`s results in easier switching to a running test.
