Feeling that DevonThink was a bit too CPU-heavy and too cumbersome to work with, I have started using Journler for managing snippets of information that I don’t really know where I would otherwise have put. After a few weeks of testing I feel that it solves a lot of the problems I have experienced with other PIM systems.
The best thing about Journler is the calendar. Since all entries are tagged with date and time, it is possible to quickly and easily write down notes, create a few links, add a couple of images, and everything will be kept together organised according to the creation date. Of course it is possible to add categories and (multiple) tags, but the calendar view is really what I like the most.
