Add buttons to indent/outdent (demote/promote) an entry in the action details panel
In the absence of an Android app (I see one will be developed), I have been using GTDnext via the Chrome browser on my Android tablet. The biggest challenge to this is the absence of a "tab" key on most Android keyboards. I have found a keyboard that features a "tab" key so I can indent an entry, however, I cannot find a way to enter the "shift" + "tab" command necessary to outdent an entry.
I think two added buttons on the action detail panel could alleviate this problem and seem to be a logical place to locate them. Perhaps, simple icons similar to ">>" and "<<" could be used with an appropriate floating tool tip.
This addition would certainly make it easier to use on an Android platform until the Android app is developed and released.
