I'd be glad if folks added their suggestions and ideas there (and/or reorganize stuff if it seems helpful) so that I can get an impression of which features are most wanted and how people imagine them to work most smoothly UI-wise.
Im not sure if it is really appropriate here, but I suggest anyway. I think for geometric drawing it is absolutely necessary to handle the units properly. Currently all units (mm, in) in inkscape's .svg is transformed to px units, and it results inaccuracy. (you cant draw exactly 3mm radius circle for example).
For correctly resolves this issue I think the "Viewbox" svg feature must implemented. (where you draw a 3mm circle as 3px diameter, and in the viewbox you specify the correct zoom parameter)
Have you thinked already about this issue?
