Editing KML files ?

I've been looking and a heap of options on google for KML file editing, and was wondering if people here had some advice ?
I've been recording walks with MyTracks (soon to be discontinued) so I thought I'd pull the most interesting walks and join the segments, keep a record for sharing or future reference. I'm looking to join the segments and remove all the timing data, opening them in Google earth makes them play as a track but can't select them together to view.
I'm open to other suggestions too, like exporting as gpx instead if it's easier. Also, what do people use to record tracks ? I'm using android.
