Thinking of buying.. More than 3 activities and long press?

[Gothicawakening]

I've been looking for a replacement for my Harmony Hub and this sounds perfect..

.. except 2 things. I can't quite find a definitive answers, lots of "in the future" comments.

1) Does it support Long Press as alternate action on buttons?

The reason is that I need a few extra quick access keys including Subtitles On / Off and Audio Track change. 
 

2) Does it support more than 2 activities?

I need 4, long press on the activities button would be fine if that works?
