Steps to reproduce the behavior:

1. Open a card with a date range property
2. It shows as "Date -> Date", but the two-character text "arrow" is not vertically aligned

Expected behavior:
Replace the two-character text arrow with a single character, → (U+2192).

It would be nice to have a function to export the elements to JSON.
Using this it should be easier to send the elements to ajax for example.

I think it would be a good idea to add something like "bottom header". For example, I want to add a button to add a new card or some information

Hello.
Currently task id is big string like '20180702151728_179455396_9237fae6e510bfd542e5cba517105482' which is fine to be too unique.
It would be great having it as simple positive integer like 1,2,3... or add another field with autoincrement(+1).
Thus it can be put in commit like 'closing task id #1' in clear way.
