Comment 8 for bug 927898

@Luca: I' ve been thinking about this a bit, but this could be quite far reaching:
- Will it be possible to have both a granular settings and global settings, and still make things intuitive; how will these interact? What happens to the global toggles if one of the granular toggles is changed?
- Lot's of GUI code will have to be added, i.e. lot' s of new buttons and toggles. This is a pain.
- We currently have 23 different snap sources, and 38 different snap targets. Should we expose all of them?
- We will need to store the snap sources separately from the targets, which is not what we do now. Something has to be done there too, because it is getting ridculous to save 61 strings similar to "inkscape:snap-source-bbox-edge-midpoints", just for 61 boolean values. This is bloating the .svg files.
