Dave..
Could you please consider adding a feature to the
AIS Target List,allowing the user to select the area of
AIS targets to be displayed in the list? Default could be ALL ,with an option to display ONLY targets within the chart area on display,or within a set radius if that is more convenient.
The reason being that in very busy areas,the target list can not cope with the extreme number of targets. Check out WebVTS Lite from Siitech which has some 12.000 vessels but only displays targets within the chart window.
I would also strongly suggest that the on/off button of the AIS display is by default set to ON and otherwise forced back to the ON position after a set period,following a selection to OFF, for
security reasons. It is easy to forget to re-set to ON after a switch off period.
