No way to delete imported tracks

Seems like there is no way to delete imported tracks. Also wish there was a way to rename them.

GREAT APP FOR BACK UP NAVIGATION

As a licensed captain this app has save me three different times in the past couple years. I was in some real hairy predicaments and having plotter trouble, the SEA IQ was a life saver giving me information I needed to navigate safely out of certain predicaments. I highly recommend every captain download the app on their smart phones if you want to feel secure in case your GPS plotter lets you down!

Our main charting tool

Although we have a full electronics suite in our trawler, when cruising , our primary charting tool is SEAiq on an iPad. The updated charts with the AIS target overlay are invaluable to us and we found this program to be one of the best bangs for the buck!
