It would be helpful to see what "operations" one can and could not do in the calculator widget.
Currently, the info button only shows four examples, even though one can do much more than that (eg, X minutes to day).
Additionally, it can be confusing in some cases where an abbreviation doesn't work but the full word does:
1tsp to tbsp -> unknown1teaspoon to tablespoon -> .33 tablespoon
or100min to day -> unknown100minute to day -> .06 day
Perhaps a page in the documentation could be created and linked to by the info button.
Or a sort of "autocomplete" could replace this altogether as units available are suggested for completion under whatever is being typed.
