In the Chart menu, the menu item for calculating relationships is called "Relationship to me". True enough, the default is to find the relationship to the default individual (I suppose?), but I still consider this a misleading title, since the chart is used to calculate the relationship to ANY person. Why not just "Relationships"?
Yes, I've noticed that it changes according to context (which in itself is problematic, I think, but that's a different issue). But most of the time I AM logged in, and I very rarely want to calculate my own relationship to the current person. I always change myself to someone else. Of course, I can do that whatever the menu item is called, but it is potentially confusing, as in "Where was it, now, that place where I can calculate relationships between people? I find the one where I find the relationship to myself, but where is the general tool?"
And that's partly the problem: that the menu item changes all the time. If you happen to be on a person page, it's "... to me", and if you're on some other page (list, report, etc.) it's the plain "Relationship". It's not obvious that they actually do the same - one has to actually follow the link to realise that they go to the same page. And since (a) there isn't even an advantage in specifying, and (b) the more specific name is actually misleading, since the link does in fact not calculate Rel2Me, but only preselects that option, it's bad design.
