Hide columns

Hi,

you did a great job with Zoho!
It would be perfect for my purpose, but I need a little feature:

Is it possible to give columns a width of 0 to hide them? (and make them visible later by selecting the column before and after the hidden column? At the moment only a width of 1 is possible but thats still too much for me ^^

Thank you!

Greetings
Matt

PS: Is it possible to save the current position when you are saving? So that the cursor returns to the same cell when you load the spreadsheet again?
