When editing the wiki, one often comes across things that either need further clarification or questions that need to be answered to make sure the information is correct. To make sure you don't have to interrupt your workflow, it would be interesting to have the ability to tag questions/clarifications in the wiki (or any other place in redmine containing wiki-input) and have them listed somewhere centrally. For instance, in the wikipage object_references (using ?+[question]+? as markup):
?+object needs reference to other_object+?Would be listed as
- object_references: object needs reference to other_object
This would make it possible to enter questions as you were are writing and finding them easily later on.
