Since i started to play with C3 i couldn't find the "show grid" option, i even i thought that it was not implemented yet, but i ended up finding it today, and i was really surprised about how hidden it's.
By now, it seems like the only way to find it, is by clicking with the right mouse button in the editor, and going to "view" and them "show grid".
I think that it would be better if the "show grid" option was located at the properties bar.
I'm not sure if it's possible, but it would be nice if we could have a checkbox and a textbox in the same line to set everything up.
BTW, sorry if i said something wrong, it's not my main language.
