I have been using OpenCPN
extensively now for a few thousand miles and have found it generally very stable and very good. There are a couple of usability issues that I would like to address but for the moment just this one.
target alarms and the AIS
alert box comes up there are two buttons at the bottom 'Silence' and 'Acknowledge'. Hitting acknowledge momentarily closes the alert box but then it's back hogging screen
real estate. On a smaller screen
it is really a pain.
I believe that hitting acknowledge should close the dialog box but leave the dangerous target red etc.. It should not instantly re-alert. Perhaps a time or distance filter could be configured to re-trigger the alert if range is still closing after two minutes or if the target has reduced the range by 25 % or something like that.
As far as i can tell this affects all versions.
