I'm running Jira 5.0.x and Conflunce 4.1.x. We do have plans to upgrade in the near future.
Is it possible to add a text box with for a link the same way that more actions -> link -> confluence page to the issue creation dialog? We have a couple projects in Jira which have a large number of Confluence pages backing up additional documentation. It would be extremely convenient to paste the link in without having to open a second screen.
