Here is a simple feature request for mainly for new users of GTDNext:
The drag&drop changing of sort orders needs to be made much easier & more intuitive! I suggest that the user should be able to click almost anywhere on any given line in order to change sort orders.
The only possible exception being should be that if you click on the actual text itself you should be able to go straight into text editing mode. This is how the excellent MLO (My Life Organised - on Windows) works.
On GTDNext you can only drag and drop if you click on the small icon on the left. But:
A) If you are a new user you may not find this (and just leave)
B) Even advanced users are still required to click on what is still only a very small target (!)
If this request is technically difficult, then I suggest using double-clicking to select the line ready to be moved.
After a LOT of research, I recently been living on GTDNext for about 3 weeks, but I am now living mostly on MLO (My Life Organised) at present.
MLO is both extremely mature and extremely powerful and I think GTDNext can learn a lot from it!
In this case, drag & drop on MLO (on Windows) is much more intuitive than on GTDNext because the user just needs to click anywhere on the line in order to select it for moving. The only exception to this rule is that if the user clicks on the text itself it then goes into text edit mode. (On MLO with the line selected hitting F2 gets you to edit the text, if that's what you really want to do. - this is also useful.)
However before everyone here charges off to MLO, I should explain that although MLO is absolutely brilliant in a large number of ways, (including it does have an Andriod App - albeit only a rather basic one) MLO does have it's own problems.
The deep problem with MLO is that it is more of a highly-configurable productivity 'platform' than and a ready-to-use productivity 'application'. i.e. MLO users can design their own system in multiple different ways. The down-side of this is that it is exceedinglyconfusing & fiddly for new users. i.e. MLO is great for Early Adopters and geeks, but is almost un-usable by Mainstream users!
Also another deep problem is MLO doesn't seem to have a field for Areas. (And if you like to work in areas, then you are forced on MLO to do a lot of messing about with tags. This is extremely painful to set up on MLO, particularly if you want to be able to do area filtering by single clicks like you can in GTDNext!).
So I am keeping an eye on GTDNext because eventually I would like to move back here when GTDNext is a bit more mature.
