As much as I love the new help viewer, I find it a bit irritating that the table of contents (sidebar on the left) is ordered alphabetically, thus “Appendix/Automation/Documents” etc with “Getting started” appearing somewhere in the middle. I know, clicking on “Table of contents” just below “DEVONthink Help” provides a more logical view of the chapters. But having a “Table of contents” entry in a table of contents seems a bit of an overkill, perhaps?
I remember that the help in DT3 was presented by chapters and sections, with “previous/next” linking in the chapters to go from one section to the previous/next. Perhaps this can be restored in a later beta?
