Automatic relation between mentioned Issues
It would be very nice if Redmine can create automatic relations between Issues when someone links the issue in one post or on the description.
Let me explain.
The user post an update on issue 1, in the update he speaks about issue 2 and links the issue (hash+2).
In this case and others cases like descriptions end etc.. Redmine can just create a relation between the two issues.
To show to user that was an automatic relation , it would be good to create a new type (not related, copy , dup ...), it can be something like Automatic Relation
This in my opinion can be very useful, because here on my work it happens a lot, that people mention other issues but forget to relate each other.
