For those who can read English but not French, sacredceltic is saying that most new users are still confusing direct and indirect translations, despite the different colors of arrows [my note: and text] that are used for each. He suggests, in addition, indenting the indirect translations.

I think that his suggestion would help as long as there were a visual element to separate the block of indirect translations from the block of direct translations. Otherwise, it would look as though there were some special relationship between the indirect translations and the last direct translation in the list (that is, the one at the bottom).

It's worth noting that if you go to the settings, the final one, under "Experimental options", is "Display sentences with the new design. Note that you will not have all the features from the old design." If you select this, you will see the captions "Translations" and "Translations of translations" in separate subsections. This is what users who are not logged in see, but it is not the default setting for new contributors.

This leads me to bring up several things that should be improved.
(1) If we think it's useful for new contributors to see a visual distinction between direct and indirect translations, we should do that by default for them.
(2) The differences between the "new" and "old" design are not documented anywhere, so they can only be determined by experimentation. This is at best a waste of time for users, and undoubtedly scares them away from trying the "new" design.
(3) "New" and "old" are both vague and inaccurate, given that this feature has been around for several years.
(4) Features should not be sitting indefinitely in the "Experimental" section. The first three items in that section seem pretty straightforward and should be well-tested by now, so I suggest moving them into the main section. As for the "new" vs. "old" design, we should figure out what we really want to do: Fix the missing functionality in the new design? Incorporate the new elements into the design that everyone sees? Offer a choice between these options permanently? Some combination of these?
