pandabear7413,
Yup, it makes sense.
Here's the thing, the people who build C3 aren't nearly as OCD as those of us who use it (;
There isn't a way to set the column spacing in the way you're describing it, sorry. I don't think they'll change it because many times we need different column spacing on different event sheets.
But if it helps, you're not alone. I am constantly changing my column spacing .... and don't get me going on the "tabs". In this forum somewhere there is a thread all about how the "Tabs" work. Some of us are very particular about our workspace setup. lol
