Just wanted to drop a note on SOGo vs WebTop. I gave the latest WebTop a spin, but for me it does not add any (better) value to me to make me switch to WebTop. I will stick to SOGo, so continuation of the SOGo app is much appreciated!.
SOGo has changed of ownership few years ago from canada IIUC to french company
It seems to get regular updates now but who knows where it goes 
released, thank mates
