The following feature request would be very handy in case of many records (I have 950 at the moment)

Please add a feature to auto check the main URL of an entry.

This should happen in the background every time the app is started.
URL that are offline should be marked internaly and be checked again at the next start of the app.
When it comes to a 3 times offline status the app could warn the user to check the entry.

And please work on the MacOS message, that the app is not optimized and has to be updated!

Thank you very much
