input field -> voice input: add "running process" indicator (spinner) after stopping a record until record is ready
Sometimes between record stop and having access to this record in the input field (= submit/clear buttons appear) some seconds go by without any indicator, that a converting process is running in the background. This confused me several time, because I thought the record broke in some way. That's why we need an "something is happening" indicator as done in the magic menu.
