Searching files smartly
When you search for a specific file, it sometimes shows several results and you can look at the items. However, it happens sometimes that you don't know which one is the relevant file that you are looking for. So you try opening one, and close it and go back, if that file doesn't have the data you are looking for. And then, when you go back, the search query results are gone. You then have to make the search query again.
You should save the search results and one should be able to get back to the search list.
