Hi.
For creating children hierarchies (sub-levels beyond the existing levels), MyInfo is a bit rigid.
For improving flexibility and usability of the tree, could you please consider implementing:
a) 'Paste as children' command
b) Drag & drop with the mouse, something like in the examples below.
Thank you,
Carlos
Create children hierarchy by drag & dropping with mouse + Paste as children command
Please note that you can achieve similar drag&drop result by dragging the note over the statey of its parent.
