Hey Bruno, Excellent idea about ripping off the history tape - love it.
I think we can explore the visual treatment of the number being currently edited. The only editable number is the last entry, it might be a different colour or something too. For clearing, pressing C clears the current entry. To remove the entire calculation you swipe the tape to the side. Sorry for the delay! Think we captured this on our blogpost too : http://design.canonical.com/2013/03/app-patterns-applied-calculator-key-journeys/ Calum On 4 Mar 2013, at 20:45, Bruno Girin wrote: > Hi Dalius, > > That looks good except for the following: > There's no backspace, > The C key clears the whole calculation and starts a new one rather than > clearing the last number entered. > As a result of both of the above, if you make a mistake, you have to start > all over again.
