1. Is this request related to a challenge you're experiencing?

In the workflow editor, I have to use / or { to open a popover to select variables. If I have a lot of variables in the workflow, it's hard to select the one I want to use.

2. Describe the feature you'd like to see

Nodes have an output area where the output variables of the node are listed. I want to be able to click on these variables and get the variable copied to the clipboard, so that I can paste it into the input where I want to use this variable.

3. How will this feature improve your workflow or experience?

It improves the UX when working with variables in the workflow editor.

4. Additional context or comments

This would be a great first issue for a frontend contribution.
