Redmine

I'm looking for possibility of defining customized views of the issue page.
Currently, selecting an issue lands with the default view on which nothing can be changed - the pdf export of the issue always looks the same. It would be great if there would be a possibility of defining custom views, ideally modifiable by a user. Then, the very same issue could be potentially viewed as 'issue acknowledgement report', 'issue evaluation report', 'issue implementation report', itc...

One way of doing this would be via custom wiki pages. Currently, there are couple of special wiki words which are interpreted by redmine providing links to issues, revisions etc. It seems to be possible to have a wiki page being just a form with wikiwords describing issue fields which would be replaced by redmine by the contents of the fields of certain issue (added as a parameter in url), together with custom fields of course. This way user will have complete control over layout of the issue displayed.
