It could be useful to review the sheets outside of the office, on site or in a meeting on your phone. Maybe not edit them on the phone but view them would be good enough.

Nice to have feature

For example I can define pi = 5 which is different to global pi = 3.14. Can cause errors in the future, for now probably OK. It is great that in the formula drop down the "new" pi displays as "pi = 5", which helps disambiguate the variables. Constants etc. could be highlighted in a different colour.

Extremely frustrating to lose progress if you click on canvas instead of pressing Enter. I would expect the field to remember whatever I entered when I click in a random space.

Expect pi to be presented as it's numeric value in the right hand side of the formula display

Very often the formula editor just does not want to be edited

Drop down in the formula editor shows active formulas and some functions, but when I click on the variables that appear nothing happens.
