[Feature request] Counter before starting the recording.

[LucioAmely]

Please add a feature to enable a counter to count down before starting the record, after pressing the record button. So we can directly start recording within our app. For example:

Press "Record" button. It counts down from a time of user's choice. We switch to app we want to record. Recording begins.

So we won't need to trim the first few seconds of our recordings.
