iGoogle doesn’t not allow users to rearrange the order of the Tab.  In order to achieve this purpose, you have to rename the tab and interchange the gadgets, this really sucks.

Again, Google Reader doesn’t allow tag to be renamed, you have to select the feed that you want to change, add the new tag, then delete old tag.

Are they just stupid or lacking female developer to consolidate their works?
