Current behavior:
1. search for an entry using the search function
2. select the entry found and copy the password, for example
3. minimize Enpass window
4. open Enpass again after a while, press Ctrl + F to search for another entry.
5. get angry because the old search term is still in the field and has not been deleted. Now the field contains "googleReddit", for instance.
Desired behavior:
[1-4]
5. the text in the search bar is marked like with Ctrl + A. This gives the user the option of completing their search (e.g. "google.com") or starting a completely new search (e.g. "reddit").
6. i find the entry for Reddit on the first try.
