there are quite some options missing, basically all of them. i am not very confident that this will still come in the version 5, but hopefully with the selection filter in version 6 then. i also cant see if this was actually tracked. maybe @dan can have a look if the options are targeted at all?
i personally would love to be able to disable the selection menu… its often in the way and always has the curves as first choice which is the only thing i need when i click at one. otherwise i would click on a surface. only when several curves partially congruent hit each other i would like to have this.
