For those of us who like it in one of the two ways, we obviously prefer it to be easy for us . Nobody would prefer to always have to press Shift. Or to get inconsistent placement just because you sometimes forget to press it. So a user preference setting is probably best for everyone.
You could still have the Shift key, of course, for people who want to alternate from their default, but personally I never want to change where my tasks land if I "toss" them onto a project heading. I want them on top. Consistently. So if that is the app's default or my personal default I do not need the Shift option.
If I want my tasks elsewhere in the project I will drag the "tossed" tasks from its default landing spot (at the top). If a "tossed" task does not belong at the very top, it usually belongs inside somewhere, quite high up near the top, more seldom further down and almost never at the bottom.
If I want to enter tasks fresh at the bottom or in a particular position I will enter into the project and insert the cursor right where I want it - that's one of the beauties of GTDNext
Are there actually any people here who prefer Latest at the Bottom? Or is that just some old "tradition" or unfounded belief that has difficulty dying away?
