I'd like to move the "created linked issue" option off the More action menu and instead on provide it as a button alongside the existing "assign" button.
I found instructions for increasing the number of buttons available on the button bar by setting ops.bar.grou.size.opsbar-operations in jira-config.properties, but I don't want to display all the entries from the More menu, just the "create linked issue" button.
I also found instructions for increasing the weight of buttons by editing system-issueoperations-plugins.xml. Presumably doing this means the action ends up at the top of the menu and can then be displayed, I haven't tried it because "created linked issue' isn't in the file.
How do I move this particular action to a button at the top?
