Is there anyway to customize the subject line of the notification emails sent by OpenProject?

Hey there,

No GUI option to customize anything about emails except the silly footer. If you're ok getting your hands dirty, you can edit the subjects in this file:

/path/to/openproject/app/mailers/user_mailer.rb

You have to make the same changes every time you update openproject because files are overwritten. Apparently email template customization is a third class citizen for openproject at this time:

I had a look at /path/to/openproject/app/mailers/user_mailer.rb What I want to do is to change the subject only for notifications that were sent because of a comment with @user. That seems not possible, right?
