In a related issue, I would like to offer an inkscape enhancemet to the developers: this is something I've been running into for a long time.
I'm using snap a lot, but sometimes it just gets in the way. Inkscape really needs a quick way - a keyboard shortcut, that is - to turn all snap on or off. Currently there is a toggle for turning both guides and snap to guides, or grids and snap to grids. But in my workflow, it happens a lot that I'd like to still see the grid but not have a node snap to it. I sometimes keep the document settings open just for that, but it takes up a lot of screen space.
I think a universal snap on/off switch would be very handy, both as keyboard shortcut and a menu item.
I already submitted a feature suggestion months ago, but I just think it was worth bringing that subject up again.
