# Observations
- `rev_handle_l` is not parented to `THR_L`, but to `MD11_THR_L_RNG`.
  This is unlike the other levers.
- Vistags were done via an animation turned PartInfo, that no longer works
  Going forward: Use a parent node (can be an empty) for all children to hide,
  hide parent node or use individual components for each.
- `MD11_OBS_AUDIO_PNL_MKR_VOL_KB` animation is keyed wrong. It has 0/100 on the
  top making a 360°. All other `MD11_OBS_AUDIO_PNL_*_VOL_KB` animations have
  zero on the left, 100 on the right and do not perform a full 360°.
- `MD11_CPT_AUDIO_PNL_*\_VOL_KB`, `MD11_FO_AUDIO_PNL_*_VOL_KB`, 
  `MD11_PED_RUD_TRIM_IND`, `MD11_PED_RUD_TRIM_SW`, and `MD11_PED_AIL_TRIM_KB`
  all have their animations reversed.
- All observer audio panel buttons and switches have no sound.
- `MD11_MIP_STBY_AI_SLIP_RNG` node is parented to `isis_digital`. This breaks
  the indicator due to the parent being hidden when the analog standby option
  is used.

# Conclusion
With the current model, feature parity was achieved with the sole exception of
`MD11_MIP_STBY_AI_SLIP_RNG`. Fixes for this node as well as the missing
animations were added via hiding of the original node and employing a submodel
to merge in new nodes with the fixes applied.

As an added bonus, the yokes are hideable. Due to model constraints the yokes
can only be hidden together, fixing this in a submodel exceed my capabilities
in blender.

Clickspot for this feature is the captain side window crank (I originally
planned to use the rubber grommet, for some reason this didn't work and the
clickspot never appeared, probably due to the, what I assume to be, skinned
mesh).
