 The following is a currently moving list of possible enhancements to be made in order to reach `v1.0`:
 - [ ] Ensure to the best extent possible a thread-safe access to the command API.
 - [ ] Clearer integration/alignment of the various I/O references between raw readline and commands.
-- [ ] Clearer and sane model for asynchronous control/cancel of commands.
+- [ ] Clearer and sane model for asynchronous control/cancel of commands (with OnKillRun in cobra)
