Problem

When using CTRL+f in the editor to find (and maybe replace) some string, the string from the last search is remembered. The user does not expect this behavior which is therefore irritating

Solution

1. When pressing CTRL+f for the first time in a task, start with empty field "search for".
2. When closing and pressing CTR+f again (still within the same task), text can be remembered, but should be selected already (so that pasting some text would replace it immediately)
3. When 2. is too much effort, just start with empty field
