I created a child of "Default Style (called "Default Style for Japanese)" to hold CSS tweaks for my Japanese translation. I selected that as the current style on the ACP "Appearance" page, and I also selected it as the default style to view when I clicked on the "Templates" link in the ACP sidebar. This morning I decided I didn't need the style anymore. I opened the ACP "Appearance" page and selected "Default Style" as the current style for my test site, then I went to the "Styles" page and deleted "Default Style for Japanese". Now whenever I click on the "Templates" link in the ACP sidebar I get the following message: To view the templates in the "Default Style" I now have click on the "Styles" link instead, then click on the "Templates" link for "Default Style". It's a tad irritating. I suspect this is happening because I didn't bother to open the "Templates" page and change the default style to view there before deleting my style. It seems the "Templates" page needs a better way of updating its default style selection in cases such as this. Perhaps this updating could be done whenever the user clicks a "Templates" link next to a style in the "Styles" page?
