Here are a couple of things I'd like to see for job variables. These are items to reduce navigation and increase productivity.

Job "variables" tab - move it from being a button under Main settings to its own tab, e.g. Main Settings, Triggers, Time exceptions, Conditions, Variables, Tasks...

Add job variables to right-click menus

• In the job variables list (where we add/edit/delete), add a right-click copy instead of having to edit the variable to access the copy button. If possible, right-click a specific column for the variable (key, variable, or value) to copy, and even show as Copy XXX the popup menu, i.e. Copy "PROCESSEDFOLDER", Copy "{JOB(Active|Variable|PROCESSEDFOLDER)}", Copy "\\SERVER1\SHARE1\PROCESSED_FOLDER".
  
• In task dialogs under the task-specific tab, in any edit field where I can paste the variable expression, provide a right-click Variables|[list of job variables] to insert a variable where the cursor is. Perhaps have two top menu items: User Variables and Job Variables, then list the child items under each. If you dare, add a third top menu item for Global Variables>categories>variables.
  

Feeding from the idea of a right-click variable access in edit fields, what about Ctrl-Spacebar to popup the job variables list so I can select it and insert it where the cursor is. Simple variable code completion? I'm more interested in job variables but the other kinds are welcome as well.
