Except the default (first in config) one, no subapps are automatically launched on app start. However, subapps configured as non-closable are often thought be be permanent, i.e. launched on start and never closed.

Currently, the only way to achieve this is creating a custom app class, iterating over all subapps and launching them.

Instead, subapps should either be markable as "permanent", e.g. thorugh a property permanent: true, or any non-closable subapp should be considered permanent.
