Store and display metric amount with an entry

[DGrothe-PhD]

Summary

As a user, when looking at the entries made so far, I want to see the amount of food, the distance of a ride, etc. I have entered for an entry. Seeing this can make it both easier to compare the pollution caused and to re-enter a similar entry next time.

Example: I put 'train ride to city A' and looked up the exact distance in Maps app on my phone. Later I want to put, say, 'train ride to town B' which is ten kilometres away from city A so I might look up how much that was and just add ten kilometers.

Proposed feature

Add a place for a stored value along with its metric unit (distance, minutes, weight), to each entry that has an amount set by the user.
Add a text label or other suitable UI element to show that value for the stored entry.
