Thanks a lot for the right to left support but it still needs some improvement
First , when you orient the sheet from right to left , the default cell direction should be right to left and when you orient the sheet back to left to right the default cell direction should be left to right.
Second , typing in arabic still does not feel right. This is how it feels in only office.
Sorry for the delay in my response . I use desktop editors , the latest version. It is actually more of a bug than a feature request. The problem is in this tool :
When I choose right to left option, the typing direction should change as pictured earlier , but that does not happen. Improving this tool would improve arabic support.
Indeed, this behavior is a bug, which is registered in our internal bug-tracker under the number 75174. We are actively working on it. Sorry for the inconvenience.
