I use TB calendar extensively and there is an extension that would be
extremely useful to me.
What I would like is once a reminder comes on to the screen, that it
persists with an audible alarm (variable time please) if the reminder
has not been accessed or otherwise ignored within the audible alarm
period mentioned above.
Does this extension already exist or is it in the pipeline?
PS I use TB 60.6.1 (64-bit) on a Linux Mint v 17.1 with 8GB memory.
