It would be very convenient to select via regular expression, for example, all IP addresses in the notes and then copy this selection to the clipboard or export to a separate note. I need that functionality. Very useful. And You can think of many examples of such use.

or maybe on some notes..

Thanks, I know that. And I already did. But sometimes it more convenient to check updates directly from the app.
Useful feature. It will be enough to see CN twitter for the news or something instead of checking CN site almost every day (like i do ;))
