RTL oriented Calc sheet?

Hi there!
I am trying to create a spreadsheet in Arabic, and I’d like to make the whole interface RTL, so the columns themselves are right to left. How can I do that?
I’ve already enabled CLT support from Tools, and I’ve tried Format Page>Page>Text direction> Right-To-Left, but this hasn’t changed anything.
Any help would be appreciated!

Ah, thank you so much! I thought I’d looked everywhere, but my menubar was hidden and the option was there all along :smiley:
Cheers!
