[Caluculator] Edit previously torn off calculation

[Christina Li]

Once a calculation is torn off, provide the ability to scroll back to edit the calculation (eg add/remove labels).

I really don't understand what is expected as description is very free. E.g. some way how I imagine it:

1) it is possible to mark specific calculation as active. But I believe that would introduce more problems as user expects that last calculation is active one.

2) it is possible to remove specific action (e.g. + 5). In this case it is not clear how UI/UX for this action should look like.

I'm not sure what is the best way to approach this problem.

1. Can you define what 'active' means? All calculations are 'active' in that a user can go back at any time to a past calculation to add/edit labels. Please refer to 'Add a label' use case: http://design.canonical.com/2013/03/app-patterns-applied-calculator-key-journeys/

2. It is true that removing an operation will become tricky as it changes the calculation, so we won't be working on this then. I have updated the bug description accordingly. thanks!

OK. I will look into labels - there might be some problems.
