I am in need to invoke certain operation screens on transition. Currently I am able to add the Attach File to a screen and all related buttons and functionality for uploading a file work.

I would also like to use work log, Clone, Link, and plug ins that add an Operation to the screen. Specifically the Clone and Move plug in to be used as the last transition in our help desk project. This would allow us to easily display a screen to clone, move, comment, Link.

I believe this is related to JRA-7661and hope you will consider trying to squeeze this in 4.0. This is related to JRA-9564 dealing with help desk.

Without this capability, it is nearly impossible to use Jira as a proper Help Desk system seemlessly move issues from help desk project to a programming project or even the example you give on your own website on moving the issue from one project for tier 1 to another for tier 2.
