Merge: Branch 'commands'

Multiple things are still missing:
- [ ] Table type support
- [ ] Error messages and Status messages in ci input field (not in the status panel)
- [ ] Better ux in the ci input field (scrollback more than one line, syntax highlighting, &c)
- For further checkboxes take a look at the `FIXME`s and `TODO`s in the code.

The base ci although is already usable and in some way useful
