Clear unsynchronized waypoints after stopped recording

[theraser]

Hi,

thanks for this great app! I use it on a regular basis and I'm missing just one small task: If I stop a session and there are unsent points left, there is no way to remove them. There is an option to clear the statistics at every start, but I found no way to (manually) clear the offline cache (marked red):

The problem is that when I start the recording again, the "old" points will be attached to the recording - it does not matter that the old recording was already deleted using the automatic cleanup process. As a result there are sometimes huge jumps on the map if the old recording was stopped far away from the point where it gets started again.
