Research history

Good morning,

**Is your feature request related to a problem? Please describe.**
I am embarrassed when I seek the same file several times.

**Describe the solution you'd like**
In the research field could I have the history of my previous research?
It would facilitate use, I think.
Even better, with the possibility of erasing history, if necessary.

Thanks.

Review the existing research field and its current behavior first; the issue does not identify a file, test, or entry point. Define how previous research should be stored and displayed, how users erase it, and what behavior confirms the feature is complete.
