Thanks for the response nanphan. I know you all are working hard, and love the product, but do agree with the other comment, it's difficult to keep my workflow in the new beta given some basic functionality is difficult (stacks, finding direct link to saved webpages/notes, merging notes). I'm going to have to revert, but look forward to you all getting the beta up to speed.
Sorry to ask a simple question here but: I can for the life of me figure out how to next a notebook into a stack. And now that I'm looking, I don't see where you create stacks either. One other unrelated note: Many of my notes are saved URLs, and I find the location of the "jump to link" very difficult from a ux perspective. Thanks!
