Search in list of earlier "evaluate expression"s in the debugger (and manage that list)

The “Evaluate expression”, together with breakpoints, offers a very useful tool for debugging. The dropdown list with expression history helps enormously. 

However, finding an expression that was used earlier is a pain. I have set the length to 500 (for good reason), but scanning it visually is very challenging.

Please add the ability to search in this list! In my list, there are many near-duplicates (typo's, but also different literal values). It would be great to be able to edit the list (e.g., remove typo's)
