Ctrl+shift to snap drawing tool to angle not working?

[nomad380]

I find suddenly that I am unable to get my brush tool to snap to an angle with ctrl+shift. Is there a setting that may have been changed while I was unaware? The tip still says I should be able to do it, but I cannot. Shift to draw a straight line is still functional. What am I missing?

Also(while I'm here), somehow my tools got grouped up instead of being displayed individually in the toolbox. It's not the end of the world, but is kind of awful. Is there any way to change it back?

Thanks for any help!
