I kind of get the general idea from this question Why do I have to drag my new apps into the application folder? that I've just unpacked an archive I downloaded. but I'm wanting to understand what the alternatives for me are and any benefits of dragging the unpacked application to a different "folder" of my choosing. Is there an advantage to creating separate task oriented folders at all?
Trying to get comfortable with my imac, but I keep forgetting that dragging into "applications" does not actually complete the installation. So why are the web download install experiences not just a one click and you are done activity? (I would use the store, but the app store far too often shows me other unrelated apps above the one I am looking for/ wastes time /distracts me too.) I feel I'm missing some obvious flexible decision point?
