We've made some improvement in this area that you might be interested in.
In the "Tree Settings" page, there is a setting for "Who you are in this tree". If you click 'set to none', then we will now not prompt you for relationships. So no more "View relationship to me" links unnecessarily if you're not in the tree.
We restored the ability to see relationships if you are an invited guest, contributor, or editor.
We fixed an unintended update in the relationship display so that it is better at taking the closest relationship to you, rather than the most direct ancestral relationship to you. So, if you are in the case where your spouse also happens to be your 10th cousin 2x removed, we're just going to call them your spouse. If you're in that situation, you should be able to click on the relationship and have it recalculate and give you the new result.
