It could be similar or different, depending on the application.

That causes an annoying direction switches.

When I worked on bidi, I decided to postpone changing the
directionality of the menu bar and tool bar until such time as we have
infrastructure to display their labels in languages other than
English.  IMO, having the menu/tool bar displayed R2L only makes sense
when the labels are in R2L script.

Thanks, I will, but it might take some time until I get to that.  Too
many things on my plate right now.
