Well, it seems the new blogger interface doesn't let you upload things like XML documents, so that was a bump in the road (my ego received a little blow as well, I thought I knew it all -that was so not the case). But instead I found something even better, I managed to revert to the old blogger interface! (where in fact it lets you upload XML documents at will and the likes). I really liked the old blogger interface, and was a little upset when they MADE me change to the new one, so I figured I would share my good fortune with those kindred spirits out there.
Step 1: On your new Blogger interface go to your Template option.
Step 2: Click on the symbol next to "Backuo/Restore" and in there you will find the option to revert back to the Old Blogger Interface.
And that's it! It's so ridiculously simple! And now I have my olg blogger interface back ^^ (once you do this you can revert back to the new one whenever you want).
Anyways, this is for those of you who liked the Old Style and want it back (just like Justin Timberlake wanted Sexy Back- good song). I hope this brightens someone's day :)
PS; Sadly though this offer only lasts for a short time, cause sometime in the upcoming months they are deleting the Old Blogger Interface T_T
