After reading many of the posts on this forum, it seems to me that we're often asking the wrong questions when we compare Logos 3 and Logos 4. I know that there are some important features
missing, but Logos has promised to add these back in fairly soon. But
more often, the missing features are not missing at all. Logos hasn’t
removed things you can do, so much as changed them. As a consequence we need to change our habits in order to make best use of the new
features. I don't think we should be asking “Why is this
feature missing in Logos 4?”, but rather “How best do I accomplish this
task in Logos 4?”
I've posted a video on my blog which explains some of the ways I've adapted my working to the new system. Perhaps others might find it helpful.
