When linking new models into your Revit model, I find that I have to always specify 'All' worksets rather than it defaulting to 'Last viewed'.
Minor thing really, however I teach Revit to multiple staff members and I'm always reminding them to make sure they check 'All' worksets when loading rather than the default of 'Last viewed'.
Wastes time having to re-open a model because all the worksets didn't load.
