As other users posts, I have some issues with the new tree layout. I feel it's about continuity...
1. The arrows. As many other testers, I really think the arrows to expand tree nodes should be to the left at all places. Having some to the right and some to the left makes my poor mouse run all over the place. The reason for this I believe is that I often don't want to click on main nodes because MC has to think for a couple of seconds while calculating merging subnodes.
2. If you don't want to expand a tree node, uncheck the "Auto expand" in Options. The problem is that this doesn't work. Bug? Yes.
3. If you only want to expand/collapse a tree node without selecting the current node, one clicks on the arrow. But you're not sure what you do since the text underlines whereever you hover. Optmially, the test SHOULDN'T underline when you hover the arrow.
Thanks!
