I have a bug fix in place for this for version 3.0.9 which I will work on releasing ASAP.

Thanks,
Mike

I'm pretty sure this is related to this thread and I'm in version 3.0.10 in my Lumi and 3.0.9 in the Samsung.
I have 2 and 3 finger taps both assigned to reset zoom/pan.  I noticed the following:
In single page mode: 2&3 finger tap both work ok.
In vertical scroll mode: they only reset the pan to the top of the page but zoom doesn't reset to 100%
In two-page mode: 3 finger tap works but not 2 finger.
In half page: 2&3 finger tap don't work at all.

Which modes behave like that by design and which are bugs. I'm interested specially in vertical scrolling and half page modes as they are the ones that I use more often.
