Colour Picker and Path Splitting

[VectorVonDoom]

Hi. I'm currently an Illustrator user but have been having a play with the demo. One of the reasons is in order to zoom in more than Illustrator allows. Few things I've not been able to work out that I'm using a lot are:

 

1) Colour picking from a reference image. Seems you have to pick the colour then select & apply rather than the normal select and pick. That wouldn't work as I'm doing a ton of them, well it would but adding an extra step's just too much when doing so many! 

 

2) Drawing a path with stroke, no fill then splitting using open path that extends past the boundaries (to then colour fill with the picker). In Illustrator you'd use Pathfinder Divide then Ungroup. I tried the Divide but that closes the intersecting path too and screws things up. Any simple way of doing that? Again I have a load to do so has to be as straightforward.

 

3) Equivalent of a default graphic style for line and fill, so I can say set it to .1pt cyan stroke, no fill and use the D key, or whatever, to use that. I know I can use styles but need it assigned to a key too.

 

Probably, hopefully all simple.

 

Thanks.
