Changeset 5639 in josm for trunk/src/org

Timestamp:

2012-12-28T02:16:10+01:00 (11 years ago)

Author:

Message:

Add a new preset option "auto_increment" that allows the user to select one of a number of given auto-increment values. This works like "use_last_as_default", only that the last value is incremented or decremented as selected by the user. Switch this on for house numbers.
