Is your feature request related to a problem?

As some streamers now use the Notes tab to describe builds in great detail (e.g. Zizaran here), I think it would be great to be able to search through Notes.

Describe the solution you'd like

I would like to have a search box in the Notes tab that searches the text within and can be auto-focused via pressing Ctrl + F as this is a well-known key binding for searching through text.

Describe alternatives you've considered

I guess the same functionality may be achieved by selecting the entire Notes tab's content, copying it into your favorite editor and using the search function there.

Additional context

Please find below a quick mock-up of what my proposed solution could look like (note the search field in the top right corner).

Beginne damit, die Implementierung des Notes-Tabs und seine Einstiegspunkte für Text-Rendering oder Eingaben zu lokalisieren. Prüfe, wie Tastaturkürzel verarbeitet werden, und verifiziere anschließend, dass Ctrl+F ein Suchfeld fokussiert und Text innerhalb des Notes-Inhalts findet; das Mock-up des Issues zeigt die vorgesehene Platzierung.
