Comment 4 for bug 170293

a) Selectable units for steps:

Initial commit in revision 10177.

b) Add spinbox for "Arrow keys move by" to Main toolbar:

The option stays in the preferences dialog for now, but with selectable units like other 'Steps' options (part of r10177)

c) Align nodes

Already part of the 'Align & Distribute' dialog when the node tool is active. For further feature requests, see bug #171287 (“Align dialog should have "Relative to" for nodes, too”) and its duplicates.

@Johan - would it be ok to assign the report to you?
