How can I add additional query parameters to a view title linked to a node?
You can do this in Views.  


Add a new field to the View "Content: Path".
Check Exclude from display.
Click on Rewrite Results and the check "Use absolute link".  
Click Apply button to Save.
Rearrange your fields so "Content: Path" is above "Content: Title".
Click on the "Content: Title" field.
Uncheck "Link this field to the original piece of content".
Click on Rewrite Results and check "Output this field as a link".
In the Link path textbox enter "[path]?return_view=myview".  (You can use the path replacement pattern because it is above the title field in the field order)
Click Apply.
