A very lamentable omission from the Template Designer screen itself is the lack of the Blogger "B" logo, which should link to the dashboard. Such a basic feature, and now it's gone.
The schizophrenic nature of the "Design" link is also disturbing.
- From the dashboard, the "Design" link leads to the "Page Elements" display. You click on "Template Designer" to get to the Template Designer.
- From the navbar, the "Design" link leads to the Template Designer. You click on "Back to Blogger" to get to "Page Elements".
The "Page Elements" GUI appears to be where we will add and rearrange the gadgets on the screen. A former "Layout" component is thus necessary for a Designer template function.
Conversely, the Template Designer "Advanced" feature appears to replace the (former) Layout "Fonts and Colors" wizard. A "Designer" component is thus necessary for a Layout template function.
One can only hope that these are merely oversights on the part of Blogger, and they have plans to remedy them shortly. I just wonder how long it will take, for them to do so.
