issue #77 - I'm unable to keep dialog visible even after rotate, but now will at least Locus store your settings before rotate.
track labels - Hmm thanks - I've simplified labels settings. It's now required to directly tap on a track to display track labels (or start "edit mode"). So now will be in settings only a settings for choose, what happen when you tap on a track and settings if you want to see a permanent label on start point with options no / simple / complex.
transparent maps in overview - I found it too, thanks. It was caused by new effect that happen when tiles are drawn. Anyway fixed, thanks.
dropbox - as gynta suggested, please try it
widget - interesting. I know that such problem was there, but at least for me, all works correctly. Latest BETA 220.127.116.11? May you try to remove and add again the widget? Thanks
