Add and option to contain grid within / outside artboards
Allow the GRID to only be on the canvas, allowing the outer space to be used at the same time for element while building a projects. ALSO allow a slider to dim down the lines and a line width slider for the lines. This way its fully customizable for the user.

Would be nice to have an option to constrain the Grid to the Artboard. Current format it is distracting to have the grid outside of your work area. I know this may also be done with Rectangle Grid. Should be an easy to add feature.
Just a thought.

Do you mean to DISPLAY grid only on ARTBOARDS (not canvas, because canvas is the area beyond artboards), AND snap to the grid where it is visible if the corresponding option is enabled?
As for the second part — please, try to stick to one request per request :)
There is existing one already you can vote for and add comments to: https://illustrator.uservoice.com/forums/333657/suggestions/32403802And thanks for the request! Grids are very unattended now.
